hello and welcome to those of you watching in the u.s. and all around the world. i'm errol barnett. >> an i'm rosemary church. protesters pack the streets of hong kong, demanding greater autonomy. leaders claim that china will not compromise. plus, as new strikes are launched against i.s.i.s., questions about the effectiveness of airpower grow louder. i also want to emphasize that no one is under any illusions, under any illusions, that air strikes alone will destroy isil. thousands of pro-democracy demonstrators are on the streets of hong kong at this hour.

many fear that a police crackdown may be imminent as they press hong kong for veto power. >> they said a short time ago, that beijing would not back down. listen to this. >> translator: china will not compromise, even if some people threaten them illegally. these actions will not make china take back the decision, in the standing committee of the national people's congress. according to the basic law, this allows the hong kong people to have one person, one vote, for the next chief executive. >> let's get the latest on the protests. andrew stevens who is amid the demonstrators there in hong kong. andrew, we just heard the current chief executive, essentially, say that, you know, one person, one vote. universal suffrage is coming.

there is going to be no change, based on what the protesters are demanding. this is the man they want out of office. how is that and his statement, likely to be received where you are? >> reporter: i don't think there will be any surprises about what he said, errol. it's not unexpected that he continues to tow the same line throughout what has rapidly become a crisis for the hong kong government and a real major issue for beijing, as well. one key word he uses there is the legality of this protest. he and beijing both clearly say this is an unlawful gathering. therefore, we are not going to give it a call to any of the protesters' demands from something like an illegal gathering. it's unlikely they're going to change at all. there's no indication they are prepared to compromise whatsoever. and they have repeatedly said that, errol. we still have a standoff. it's interesting.

the chief executive talking about that one person, one vote. he is absolutely right. in 2017, there will be one person, one vote in hong kong. the problem that these protesters say, is beijing will choose who they can vote for. they will be able to vote. but the nominations will be carefully vetted. to them, that is not full democracy. beijing says this is a step towards democracy. let me step out of the pick chur so you can get an idea of what's happening here. as i've been talking to you over the last couple of hours, the numbers have really begun to swell here. now this, is the key protest site. you'll notice there are a lot of people wearing black here. that black was a -- it's a solidarity move, really. it was called for by the students union, after the police had opened fire with teargas and

pepper spray on sunday evening. and we have seen several arrests and several injuries. as a result of that, more and more students came out to protest. more and more nonstudents have come down to offer their support. actually, backfired pretty badly for -- as far as the police were concerned. and they did take a lot of criticism. we're seeing very little police presence here. we haven't seen much of a police presence for the last 24 hours or so, which is emboldening more people to come out. tomorrow is a public holiday here. a lot of people saying you're going to get a bigger turnout when people aren't working to show their support. a crisis which continues to grow for this administration, errol. >> i want to pick up on the word you used, emboldened. and he said the sentiment was it encouraged them to keep showing up. the fact that the government pulled back the riot police

showed almost like a moral victory. that the demonstrators were right. he says of the next few days, a as you just mentioned, he expects the crowds to grow. does the local government there, does beijing really comprehend what they have on their hands right now? this looks like the beginning of a real, genuine, you know, anti-government demonstration. >> reporter: yes, a movement. i think they are aware of the potential here, errol. it appears to be strategy, if you like, appears to be from authorities here, is to let the students, let the protesters have their moment. that may be over the next two, three, four days or whatever. and eventually, they're looking or hoping that there will be some sort of backlash against this. this is very much a commercial town. i'm standing on the edge of the financial district. that big gold building behind my

right shoulder is the start of the financial district here. hong kong is hurting. there's no doubt about it. it is disruptive what's happening here. not just here. two other key spots in town. but also, thousands of protesters. and the government is estimating, there's going to be backlash. when you get the backlash against this occupied hong kong movement, when people start realizing that the economic hit is becoming significant, which the government says it will become, you may see a change of heart from the government, more aggressive response. but it's a very, very fragile issue for this government to deal with. they're used to having big protests here. hundreds of thousands of people coming out. but they're not used to having this sort of focus on one particular issue. and to be honest, you can hear right now. you hear those chants coming up. all around these thousands and thousands of people. there's a lot of passion here. a lot of drive. as you say, there's a feeling that the police did back down

after that teargas move on sunday. they feel they have the upper hand. and they are going to keep pressing that. >> andrew stevens is live for us in hong kong. it's just past 3:00 in the afternoon there. you're hearing the crowds chant. the numbers there, growing, as each hour goes by. and the standoff remains. andrew, we'll, of course, check in with you throughout the day. thanks for joining us live here on cnn. ♪ all the tension over hong kong, comes as leaders mark martyr's day tiananmen square. it comes a day before china's national day.

an i.s.i.s. advance. and a question of whether coalition forces are doing enough. i.s.i.s. is closer than ever to capturing kabani. they are three kilometers east of this key kurdish city. if it falls, i.s.i.s. will control a 100-kilometer section of syria, that stretches all the way to the turkish border. >> so far, the u.s. and its allies have bombed more than 200 positions in iraq. and xloes to 60 in syria. the latest targets are in and around the cities on this map. the u.s. air force has carried out three-quarters of the strikes in iraq and half in syria. >> the question so many have are how much pain are those a airstrikes inflicting on

i.s.i.s.? >> reporter: the latest i.s.i.s. video from syria, claims to show a coalition air strike. an i.s.i.s. fire agent the jet from the ground. the video cannot independently be confirmed. when it comes to air strikes, the u.s. is not promising results. >> it's going to take time. >> reporter: this u.s. military video shows another air strike. this time, hitting an i.s.i.s. compound here kobani, where the latest i.s.i.s. move is being fought. one resident in the city tells cnn, i.s.i.s. fighters are advancing and may be as close as two miles away. if they take the city, i.s.i.s. would have free reign from its self-declared capital to the turkish border. but there's been just a handful of air strikes here, a stark

example of the limits of air power. pentagon officials tell cnn so far, the military does not have orders from president obama to protect the kurds in syria. so, strikes are few for now. hitting only at i.s.i.s. targets the u.s. wants to destroy. while refugees are trying to escape by the thousands. from the defense secretary, a chilling warning about anticipating success. >> i want to semp siemphasize, noun with is under illusions, that air strikes alone will destroy isil. they are one element of our broader campaign against isil. >> there are other limitations to what airpower can accomplish. >> airstrikes don't work if you don't have good intelligence. >> we have gone past the idea of going after an area without intelligence soernlted with the targets in that area.

>> the 60 u.s. and coalition air strikes in the area, have had impact where's the booms have fallen. >> airpower has been decisive in a couple key areas. preventing the amassing of forces on a large scale. degrading isil's command and control ability. and working to impact isil's financing. >> reporter: u.s. fighter jets will continue to patrol the skies over syria, continuing to look for i.s.i.s. targets. barbara starr, cnn, the pentagon. as you all know, jordan is one of the arab countries going after i.s.i.s. but support for the extremists is growing in at least one corner of its own kingdom. we go to amman, jordan, for the details. it does beg the question, why are we seeing this growing support for i.s.i.s. in that part of jordan? and what is the government there

doing about it? >> reporter: well, this is not the only city in jordan where you find support or sympathy for isis. it's been a key base of support for jordan's monarchy. >> the center of violent riots and confrontations with security forces. but perhaps the most worrying for jordanians is scenes like this in recent months. small protests in support of i.s.i.s. while many downplay the demonstrations, the street tells a different story. pro-i.s.i.s. d pro-i.s.i.s. graffiti is across the city. i.s.i.s. supporters were not hard to find in the city's market. this man interrupts our interview saying the only solution is the islamic state. others, too, say they want to

see i.s.i.s. in jordan. we hope the mujahadin come here and enforce sharia law. most are opposed to jordan joining the coalition against i.s.i.s. >> translator: for almost four years, our brothers in syria have been bombed. civilians and children killed. mosques destroyed. and we haven't seen the u.s. jordan's a military and the arab armies move to support our brothers in syria. but when it came to the mujahadin, they mobilized all their armies and started striking. >> while this key u.s. ally faces the danger from i.s.i.s. on two of its borders, many fear the threat from within will only increase now. the mayor says joining the coalition was not in jordan's interest. >> translator: the jihadi movement has been in jordan for

years. not just here. but in other cities. they will not hesitate to carry out operations here. >> reporter: like many of the city's residents, unrest stems from poverty, employment and years of isolation from the government. back on the streets, i.s.i.s. supporters insist, only an islamic state will bring them a better life. and that dream of islamic state is now under attack. people are repressed. a lot of pressure will lead to an explosion. wait and see, it will not pass peacefully, this man warns. for now, it might just be words and threats. many fear what the future may hold. rosemary, while support or sympathy for i.s.i.s. does seem to be on the rise, since jordan

joined that coalition, last week, also, there are reports of a stepup in the crackdown by security forces on jihadists here in jordan. according to one defense lawyer who represents suspected jiha s jihadis, he says at least 15 have been rounded up over the past month alone. >> many thanks for you bringing us that story. incredible. go to errol now. >> thank you. we want to get you information from the u.n. general assuesemb now. where the prime minister says not to forget about other threats. benjamin netanyahu told delegates, if they don't want i.s.i.s. to enrich uranium, than iran should not be allowed to, either. take a listen. >> many of the countries

represented here, rightly applauded president obama for leading the effort to confront i.s.i.s. and yet, weeks before, some of these same countries, the same countries that now support confronting i.s.i.s., opposed israel for confronting hamas. they, evidently, don't understand that i.s.i.s. and hamas are branches of the same poisonous tree. >> palestinian leaders, though, are dismissing the israeli prime minister's warning with sharp words of their own. >> you can tray to say whatever you want. but when you kill 2,200 civilians, majority of them are children and women. and you're injuring 11,000

civilians, majority of them are children and women, these are fact that speaks for themselves. >> palestine liberation organize, called the prime minister's speech a manipulation of the facts. a short break now. but for thousand, it was a refuge from war. now, spanish officials fear malia may be a passage way for i.s.i.s. fighters.

welcome back, everyone. police in australia are carrying out counterterrorism raids in melbourne. >> one man has been charged with providing $10,000 to a terrorist organization. a u.s. citizen could travel to syria. australia's prime minister has expressed concern over the number of australians believed to be joining and supporting militant groups overseas. earlier this month, australia's national security agency raised its threat level to high for the first time. some of those refugees can be found on what's being called europe's most dangerous border. fortress-like fences separate the territory of melilla.

>> a triple layer of barriers fencing off this enclave from the rest of north africa. but it's not enough. thousands of desperate migrants make they're way on to europe's doorstep. many end up here. originally built to house 400 refugees, it now holds more than 2,000. this is a kurd on the syria/turkey border. many of his family members are fighting to hold off an i.s.i.s. advance.

>> reporter: he says there are more than 1,000 refugees here. 150 from kobani alone. authorities say they'll need permission to enter the center. but he and some of the other refugees showed us these pictures. depicting, they say, the squalor inside. often, they tell us there's nowhere to sleep. many say they spent their last savings on buying a forged passport to get here. moroccans are allowed to enter melilla to work and trade. that's been used by gangs smuggling people looking far better life in europe. now, the spanish authorities fear it's being exploited by would-be jihadis. once in me leila, it's just a

boat ride away. i asked him, how much? every day, they say 10 to 15 more syrians arrive. walking right past the spanish authorities. a back door into fortress europe. on the mud track, spanish army vehicles take up position. they won't tell us why. but tensions are high, since authorities arrested a man to be the center of a cell last week. the latest of 20 arrested here on terror-related charges. the spanish government has admitted it's worried that not

all that come here are simply seeking refuge. for syrians trapped so far from home, it feels like once more, they're caught in the crossfire of the war between i.s.i.s. and the west. when we come back, a dangerous situation in japan. there have been more tremers on the country's mt. ontake. we'll show you how that's affecting the search and recovery efforts, as ash and gases continue to spew from this active volcano. >> the only people going up there are the rescuers who are putting their lives on the line to bring back injured survivors. also, bring back the victims.

criticized for its handling of the disaster. volcanic quakes are hampering search crews on japan's mt. ontake. you see compelling footage from this part of the world. 36 people are believed to be dead after a sudden eruption on saturday. 12 bodies have been brought down so far. will ripley has more on the recovery efforts and the loved ones who are waiting at the base of this volcano. >> reporter: this roadblock is as close as we are safely allowed to get to mt. ontake. the emergency vehicles coming through here almost continuously. the people recovered from the mountain, to the area where their bodies are identified. the ash continues to rain down on us. that's why we have helmets and are wearing face masks, at time when the air gets thick. you see the seismic activity continuing to happen up on the mountain. the only people going up there are the rescuers, who are putting their lives on the line, to bring back injured survivors.

also, bring back the victims. place them on ambulances. and carry them away. those ambulances come here to a former elementary school that has now turned into a morgue. the people pulled from the mountain are taken and identified. a few minutes ago, we watched another one of these ambulances come. and they pulled a body that was wrapped in cloth. it's a scene we see playing out here over and over again. after a body is positively identified, it's time to notify the family. this man's son and girlfriend were on the summit just before the eruption. it's the same area where rescuers keep finding more bodies. you can feel his grief. it's a grief shared by so many families. their loved ones climbed that mountain. now, they're making their final

journey home. will ripley, cnn, mt. ontake, japan. >> we will turn back to our top story next here on cnn. democracy protesters, sitting tight, despite a strong message from hong kong's chief executive to stand down. we are live in hong kong.

thanks for staying with us on cnn. i'm rosemary church. >> i'm errol barnett. i.s.i.s. is gaining more ground in the battle for kobani, syria. sources tell cnn its fighters are just three kilometers away. if this city falls, i.s.i.s. will hold a 1,000-kilometer

section of turkey. hong kong executives say china will not compromise to the illegal threats of some people. protesters remain camped out on a main street leading into the business district. they're demanding the central government allow an open election in 2017. right now, only candidates approved by beijing can run. china is now blacking out cnn's coverage of the hong kong protests on the mainland. cnn's andrew stevens has been right in the middle of it all, talking to protesters. and he joins us, now, live. it's about 3:30 in the afternoon there, andrew. it started to get a little cooler. more people are coming out, as people finish their jobs. and that's not going to end. people have vowed they will stay out there. now, of course, they're hearing, through their own chief executive, that china will not compromise. what are protesters saying to you about that?

>> they're just not surprised by these comments coming out of beijing, rosemary. all along, beijing made it crystal clear this is an unlawful gathering. illegal gathering. as has the administration of hong kong echoed those words. they're not going to be listening to protesters demonstrating on the streets of hong kong. and beijing does say that this is a step, what has been put into place, as far as the democratic process here, is a step forward. there will be universal suffrage voters in 2017. the sticking point, of course, is who nominates the person or the people who will actually stand for that election. and that is very much still in beijing's hands. that is what the hong kong protesters here want to change. just quickly move out of the way so you can get an idea of the scene down here now. it's reminiscent of yesterday. getting towards late afternoon. you get a big influx of

protesters coming in. also, people just coming down to see what's going on. these streets, you're looking at a ten-lane thoroughfare here. now, covered by tens of thousands of -- remember, rosemary. this is just one spot. this is the main protest site. there are two others in hong kong. and those words from the chief executive about no compromise, will certainly mean that the protesters will also be digging into their side of the story. they're not going to move until they get the changes they want. so, we have a standoff. and on that note, i'd like to bring in david now. he is the director for the center on chinese transnational relations. he joins us from our bureau in hong kong. david, great to have you on the show. you've been watching developments on both sides. very well. thank you, sir. you've been watching

developments on both sides for many years now. put this in context for us. how do you see this as the severity in the opposition to beijing, coming from hong kong? just how significant is this? >> well, i actually am quite surprised. two, three days ago, i would have thought that beijing was going to crack down, probably tonight. i think that with the 65th anniversary of the founding of the prc, he does not want to be seen as someone who can't manage a bunch of students down in hong kong. so, we know they're not letting the people in china see this. but if you look at this from a domestic political perspective, a lot of chinese, a lot of people on the mainland would say, he's got to protect himself. he's not completely consolidated. he wants to push through reforms. and he can't afford to be seen to be soft. same thing for him. he can't be seen to be weak. if he's weak, he's gone.

>> are you suggesting that there is going to be a very confrontational end to this. there will be a crackdown at some stage? >> i would have thought it would be sooner. and we've seen all these -- reasonable concessions. we've seen the police taken off the streets. the riot police being ds-- backg off. they're being hard-nosed. if i were the students, i wouldn't push beyond sunday. i think that some people think they shouldn't push beyond friday. i think the fact that they've been able to hold the downtown area, virtually captive, through july 1st, for them, they should say, we did it. we stood up to beijing. i think we're going to hear around 4:30 this afternoon, from the -- one of the student

leaders, saying what they're strategy is. if i were them, i wouldn't push it too much further. >> yeah. that's right. we are waiting to hear what the student leader is going to say. i talked to the students down here, david. and to a person, they are absolutely firm on their intention to stay here to continue to occupy until there is a change of political system or the change of the way that the candidates are dominated for the next executive. is there a compromise here -- >> that's a problem. >> with both sides can talk away? >> in some ways, if i were the students, i would walk away. maybe there's room on the nomination committee that they can say we're going to have a much more open -- many more democrats. it won't be as tightly controlled. the other thing i think about is, just because beijing has said -- let me say this.

a better -- beijing could say, look. this is what we're doing in 2017. by 2022, we will have introduced more serious reforms through electoral process. we will sit down with you in the next few days or, you know, in a couple of weeks and have a meeting. and we will lay out -- maybe the next few days. we will lay out some thoughts about where we could be for 2022. we're fixed on 2017. but by 2022, we could have some more openness to the process. maybe that would work. maybe that would be one-third way. >> just very quickly, david. >> this isn't easy, you know? >> how far up the chain of command has this gone in china? >> oh, i have no reason -- i can't answer. there's no doubt that it's reached to the number three

person in the bureau standing committee. he's responsible for hong kong awares. there's the leadership group. on hong kong affairs. and he's running it. but i can't believe that he's not checking in all the time. and making sure. we've -- this is pretty much his -- i think his show. >> all right. we have to leave it there. thank you so much. >> good to talk to you. i'll see you tonight. >> okay. rosemary, putting in a bit of perspective. interesting that he thinks it's unlikely, that the supreme leader in beijing is not being briefed on what's going on here in hong kong. just quickly, to recap, tomorrow, things get interesting because it is a public holiday here. there is widespread expectations, a lot more people are going to turn out.

there's tens of thousands of people here now. you look around, still a lot of them are students. a lot of younger hong kongers here. tomorrow, with the public holiday, it could be a big, big swelling of those numbers, which is going to put a lot of strain on the police here to deal with it and to keep it orderly. tomorrow could mark a significant development. significant stage in the evolution of this dispute here in hong kong, rosemary? >> it certainly could. the only things that have stopped people out on the streets at the moment, is it's very hot. but people have been going to work. after they're finished work, they've been coming back on the streets. they won't have work to go to tomorrow. that will be a different situation. andrew stevens, many thanks to you. bringing us an update there from the streets of hong kong, live. now, for a different view on the protests. i spoke with robert chow, spokemans for the anti-protest alliance for peace and

democracy. he says he supports the call for democracy but not the protests in the streets. take a listen. thank you, sir, for talking with us. i'm interested because you really don't think that the demonstrators out on the streets in hong kong, that's the way they should do this. what are you suggesting they should do instead, then? >> i have no idea what they should do. but they should not be holding hong kong hostage. they should not be interrupting people's life. 1.5 million people have signed their names, put their signatures on paper to tell them we do not want occupied central. now, that it's happened, what are they going to do? they can occupy the streets for a couple of days. maybe have fun. please, don't interrupt common people's livelihood. day in and day out. they have to consider what they're going to do. >> let's look, then, aed why

they're there. they're there because they believe china is infringing on their right to democratically elect the leader of hong kong. fair enough? >> everyone in hong kong wants universal suffrage. 1.5 million people signed their names to a campaign that says we want democracy. we want universal suffrage. the question is how do we select candidates for the election. now, this is something that ought to be discussed. there is going to be a consultation going on. you know, frankly, we should talk instead of, you know, occupying the streets and disrupting people's lives. >> robert chow, talking to me a short time ago. i kept talking to him. but he wasn't coming up with alternatives. he didn't think people should get on the streets. but he said he believed they had a democratic right to select who they're leader was.

if you're going to criticize with people going out in the streets, you have to come up with an alternative. >> i thought it was interesting, that they said the same thing. this is a big win for the young people and the demonstrators. but not to take it too far. not to demonstrate for the rest of the week or for weeks on end, at some point, the hammer could fall. >> the economy's going to determine it. in a few days, when the business and the investors start saying, okay, enough. that, will then give the government an opportunity to say, okay. we're done. >> we're staying with this. we'll have more on the hong kong protest. about 15 minutes, we'll look at the cat and mouse game being played between protesters using social media and chinese censors. coming up, new details on two white house security breaches. and the questions they're raising about the agency responsible for the president's safety.

hamid karzai refused to sign the

deal. there's more than 28,000 troops in afghanistan. under this deal, the number will be scaled back to 9,800 by next year. by 2017, there will only be a few hundred u.s. troops still in the country. the agency responsible for protecting the u.s. president is under fire after two white house security breaches. one involved an intruder who had a knife. jumped the white house fence and ran right into the mansion. he made his way all the way into the east room before getting tackled. brian todd reports on the continued fallout for the secret service. >> reporter: the white house fence-jumper swept past a secret service officer and ran around the main floor of the house. that's according to congressman jason chaffis. the intruder was inside the east room of the white house when he was finally taken down, i

cording to "the washington post." the secret service claimed the man had been captured after entering the front door. the secret service would not comment, citing an ongoing investigation. that comes on the heels of an earlier report, claiming the white house came under attack in november 2011. seven bullets hit the white house. one smashing a window, just a few feet from the first family's living room. the president, first lady and daughter, malia, were not home at the time. but the younger daughter, sasha, and the first lady's mother were inside. how bad of this could have been? >> clearly, had the grandmother and the daughter been on the balcony, it would have been a dangerous situation. >> reporter: the shooter sped off, crashed his car a few blocks away. he was arrested five days later in pennsylvania. according to the new reporting, secret service supervisors told agents to stand down immediately

after the incident. claim nothing shots fired. and it wasn't until the cleaning staff discovered the bullets four days later, that the secret service realized there had been shots fired. critics are, again, blasting the secret service. >> they're not safe. absolutely not. the agents i talk to say there's a miracle there has not been an assassination so far. >> the secret service is pushing back hard. telling cnn, the agency did not bungle the response or the investigation. they claim agents were hold to stand down immediately afterward, because of the confusion of the moment. witnesses had reported people from two cars had fired at each other. as for not finding the bull elts for four days -- >> the bullet pierced the historical glass. it didn't go through the protective coating of the white house. when you're examining the white house from the inside windows, there were no breaks in the protective glass. >> reporter: michelle obama was,

reportedly furious with the secret service over the incident. the first family was concerned about the incident. and unhappy with the slow response. but not furious. an official says the first family has confidence in the secret service to do its job. brian todd, cnn, washington. let's talk about what will taking place behind where brian was. india's prime minister will meet with president barack obama for the second time in a matter of hours from now. he arrived in washington. the leaders are set to meet on tuesday. they have a number of issues to discuss, including economic growth, security and climate change. if you haven't heard, and i'm sure you have, bill and hillary clinton are now grandparents. and now, we have video of their new pride and joy. daughter, chelsea, left a new york hospital monday, with baby daughter, charlotte, and her husband. charlotte was born on friday.

she is the clinton's first grandchild. very cute. >> very happy family. more happy folks for you. george clooney and amal a alamuddin, are husband and wife. they approached the government building where they exchained vows. here they are after the ceremony. do we have the footage? their private weekend wedding, that included star-studded guest list. next here on cnn, getting the message out can be a challenge for protesters in hong kong. we'll show you the app they're using to communicate. i'm only in my 60's.

it could blow again. >> that's the major concern here. just because of what you said, errol. the increased activity being reported by officials in this portion of the world. this volcano has erupted many times in the past. most recently in 2007. it was a minor eruption in 1991. it was a minor eruption in 1979, a major eruption. 2,000 tons of volcanic ash in the atmosphere. this past saturday, it was 1 million tons of volcanic ash. what's the difference is that subsequent volcanos did not happen with the three previous activities that we just spoke of there. no increased earthquakes, no magma movement. this particular event had all three of them and it's continuing across this region. a lot of discussion in place why there was no advanced warning for this.

and the japan meteorological agency is saying we did issue a warning on the 11th of september. saying there was increased active. but nothing to warrant concern as far as the warning levels, which are at the lowest level of category. it was one. now, they've been raised up to three at this point. everyone needs to stay off the mountain at this hour. volcanic earthquakes, usually the tell tale sign that things will go bad quickly. this one, minimal in that. that's why the warnings were kept localized in this region. there was no swelling or ground deformation. no lava dome forming around this particular one. and the gases we're reporting seeing was not prevalent leading up to the eruption. this is going to show the activity, as far as the sulfide being released. this gas is colorless. it has a foul odor. it resembles rotten eggs.

it's poisonous, hence why they're pulling people off the mountain. and it's flammable and explosive. with all of this said and the increased activity, we know that conditions could get very dangerous in the coming days. and potentially, in the next couple of months, before things calm down because, as i said, the past quakes, eruptions, had shut off onthat. this one seems to be breathing after the initial eruption. >> it's very much a concern. and hopefully, what will come of this is a better warning system and a better way to filter that news out to people. >> absolutely. we saw it in japan in 2011, with the 9.0. hopefully the same goes here. at this moment, rosemary and myself, and cnn's coverage of the hong kong protests is being blacked out in mainland china. >> the censorship started a short time ago. you're watching there before it gets blocked out. it's -- there it is. a bit surprising, in fact, that

our reporting was ever allowed to air for as long as it did. china's government began censoring social media sites after the protests started last week. but in hong kong itself, protesters are coming out with new ways to spread their message. samuel burke explains how they do it. >> reporter: instagram has joined the long list of social networks unavailable behind china's firewall. protesters were uploading their images to instagram, as was our reporter there. you're seeing his pictures on the screen right now. the images could be viewed in mainland china until sunday, when chinese censors appeared to block instagram. you can check web sides like blacked in china to see what sites are blocked in mainland china.

outside of mainland china, protesters in hong kong have not reported censorship of social immediamedia media. but say cellular internet connections are moving slowly. many have turned to the fire chat app, which doesn't need an internet connection. it allows you to send text messages and photos. but uses a combination of bluetooth and wi-fi to send messages. the company says it was downloaded more than 100,000 times in hong kong alone, between sunday and monday. samuel burke, cnn, new york. >> censored or not, you have been watching cnn's special coverage. we appreciate it. i'm errol barnett. >> and rosemary church. >> if you are watching in the u.s., stay tuned.
