that's all for us tonight. we'll be back tomorrow at 9:00 eastern. anderson cooper starts right now. good evening to our viewers here and watching around the world on cnn international right now. a police crackdown on protesters picking up again over the last several hours in turkey, now spreading to turkey's capital. this is taksim square in istanbul. what began as a protest last month has evolved into something bigger. what you're seeing has ebbed and flowed throughout the evening. police moving in, then

regrouping. many protesters leaving. some digging in. the situation heating up again within the past hour or so. there are now reports of unrest in the turkish capital, firing tear gas overnight, toward apparent protesters as armored vehicles cleared makeshift barricades along the streets. the latest chapter here in taksim square is still unfolding. police moved into the square, some of what you'll see and hear are not gunshots but protesters setting off small fireworks and the small of tear gas canisters firing. much of what you'll see and hear is chaos with our correspondents right in the middle of it. thousands of demonstrators. we were standing here when an

altercation broke out. >> we don't know what sparked this police move. there was an altercation. they've been seeing that all day, so no specific reason why that itself would be the trigger of much an enormous response by police. i'm just letting you see the fireworks going off behind me now. it's unclear if it's celebratory or being fired at the police as part of the protests. we're seeing people run away now, scattering. it's not quite why we haven't heard the crack of tear gas again. there we are. so much of the danger of people in these situations is that fear of mass panic where people run in a direction for up known reasons. here's the banging again.

>> right now i'm in the very front of the park. you can see people trying to help us out, because of the tear gas. the entire front part of the park has been cleared out because of the intensity of what was just fired in. people are angry and infuriated at the way the government has been handling all of this. but it's become a bit of a routine. tear gas is fired in. people clear out, then they move right back in. >> just a couple of seconds ago, a minute, a massive volley of tear gas from the police in that direction. and now one, two, three, i'm going to have to put this gas mask on i'm afraid. >> this has been going on for hours now. the situation continues to unfold. our correspondents are still on the scene and they join us now, along with christiane amanpour. she recently interviewed the

turkish prime minister. and ive nick, explain your vantage point, where you are in relationship to where arwa is and what's happening right now. >> reporter: right behind me, anderson, just as you started talking, we've seen these fired towards police for much of the night. it seems to be the weapon of choice. i'll give you a moment to listen to this. it appears to be the weapon of choice of protesters. the situation down the street closest to me, we're talking about a square here in a park. arwa, when we saw her earlier, she was on the far side. i'm on the near side. down the left, people made a substantial move and pushed a lot of armored trucks, water n

cannons, pushing everybody back. in the last half hour, protesters seem to have crept back up that road. and that i think is where those fireworks were fired from. so it begs the question, what is the police strategy here? how do they intend to remain control of the territory as they push forward? we've been asking this question for much of the night. hard to really understand exactly what their final game plan is. tear gas now being released in that area. that is the standard tactic, when they see your position they fire these enormous volleys of tear gas cannons. they drift across the square, often blowing with the prevailing winds into our position here. i'm hearing the shouts of protesters right now behind me down that road. we had thought that much of that protest had been pushed back, but we saw some of the armored water cannon trucks move in, in fact firewater cannons into gezi

park itself. we're just now having seep for about two hours pretty much calm in this larger part of taksim square, as the police used bulldozers, the barricades and sending them off. things appear to have been under control, but now we saw those fireworks and there's clearly a bit of fight left. >> nick, we have been watching bulldozers move in, as well as columns of police. are they not occupying and holding territory, the police, once they have taken it? or you say protesters, in some cases, are moving back. how is that possible? >> reporter: if you can imagine a square that is the park. on one side of the square, closest towards the main streets of this massive turkish city, they're clearing away the

street. the two side roads that go down the streets of that particular park, they still seem to be contested. what's closer to me here, there are still protesters there. i believe that they're small in number. i'm seeing flags again near the barricades too. so yes, the confusing thing has been the absence of a police strategy to retain control of territory. it may be they're lacking in numbers, or if by doing that, they would end up in continued confrontation with protesters. a loud bang behind me here. sometimes that is a plus stun grenade. sometimes tear gas. that did sound more like a firework. hard to fell at this particular point. they seem to be firing down the far road away from me here on the other side of the park.

you can now see police moving down that far road. i've been down there last night. there were buss in the way for barricades. it heads down to one of the hotels. but after those moments of calm, again, we're hearing blasts here in the very heart of istanbul. 19 hours now of this. hard to understand why police would want it to go on this long. when you know what turkey is tch normally like. at 3:07, 3:08 turkey time in the morning. nick has been standing there 18, 19 hours. i want to check in with arwa damon, who i believe is on the other side of if square. explain where you are in relation to nick and what you are seeing right now. >> reporter: i am on the other side of the square from where nick is. and we are holed up inside a hotel that has kindly opened its doors to us and dozens of other

demonstrators have set up a makeshift clinic. i can barely see the park that is less than 20 feet across the street from me, because the smoke from the tear gas is so thick at this point in time. nick has the vantage point on this, but the demonstrators have been occupying, they were clashing with riot street, and then there was an intense volley of tear gas. causing complete chaos, people running into the hotel. then we saw the army vehicles driving down the street, pushing all of the barricades away. there were a handful of demonstrators that went back out and now the tear gas.

[ inaudible ] they're not letting anyone out. >> arwa, i want to show our viewers what you experienced and the people around you experienced just a few moments ago before we went on air. let's take a look at that. >> reporter: they're rallying around one another, as well. you see a lot of them pouring this white liquid into each other's eyes. that's actually something that helps ease the sting and the burn. [ indiscernible ] while the riot police have not entered the park itself, the tear gas is now landing inside the park.

if i just move around here -- where those clashes were taking place between demonstrators and riot police. [ indiscernible ] some of the demonstrators trying to push their way forward right now. they've been screaming "be careful" to one another. when you see this happening -- [ indiscernible ] it's so densely populated here and the tear gas canisters do --

[ indistinct yelling ] >> reporter: you can see in front of our cameras right now, some of the demonstrators are trying to collect stones -- >> arwa, in terms of what we're looking at, let's look at it full screen. what is going on? you're wearing the gas mask, so it's hard to understand what you're saying. explain exactly where that street is, and then what happens in this video. >> reporter: so that particular video you're watching, that is

the same street that nick has the vantage point on. i'm currently on the other side of the park. >> we just saw video of a guy dropping to the ground. >> reporter: we had to move back. and then we were unable -- we were unable to move back adequately enough. they ended up evacuating the park with the demonstrators, coming to the other street on the completely separate direction. and that area had an intense volley of tear gas. so right now we're inside the hotel. i can still see the tear gas billowing ever parts of the park right now. >> arwa, let me -- arwa, we see protesters in this video. it looks like a protester drops

to the ground. they looked like they're picking up tear gas canisters, throwing it back at the police. has that area now been cleared? >> reporter: we actually moved away from that area into another park. since this happened, the protesters clear out when the tear gas gets fired in. then they slowly trickle back. that's what we're seeing happening in the area that we're in right now. >> okay. >> reporter: a lot of these protesters, anderson, they really came up just wanting to highlight one thing, that they would consider themselves a -- but they feel as if they do have to go out and stand with the others that are in the busy

parks themselves. most of them are people, they're professionals. they go to work in the day and demonstrate at night. everyone is so shocked and angry how the government is handling all of this. >> that was arwa damon. we have to take a short break. we'll be joined by christiane amanpour in just a moment. also, professor fouad ajami. we'll be right back. ♪

up. vo: opportunity, that's the real walmart. welcome back. you're looking at taksim square in the middle of istanbul. this is earlier today. we've began seeing armored trucks pushing people back, protesters launching fireworks. christiane amanpour joining us now. also is professor fouad ajami, senior fellow at stanford university. you've been talking to turkish officials all day. what do you make of this?

>> there's one huge question to state the obvious, how is this going to end? all sides have their backs to the wall. there's no sense of how there's going to be any kind of common ground reached. the prime minister started all this -- not started it, but once it started, started calling them rift raft, now he's trying to make a distinction between legit mall protesters and vandals. there's going to be a meeting tomorrow, but now what i'm told is this is going to be a singer, artist and actor, people close to the government, that have nothing to do with the protesters. how is that going to change? what i was also told by a chief adviser to the prime minister is there are designated areas of protest, gezi park and where the people are, i was told is going

to remain a protest zone. it's just a few steps above taksim square. and the police are not meant to enter there. what we saw in taksim square was also announced by the mayor tonight who said people, stay away for your open safety. we are going to clear the square. the police are use unremitting efforts day and night to clear the square. >> what is this about and what do you make of this? >> this is the biggest civil disobedience we've seen in turkey in a generation. there are a few fringe groups, communists, socialists that have molitav cocktails, but for the most part, this is a young generation of turks, guys i know like rock guitarists that just smoked pot all day, who has been out, mobilized somehow grassroots out of nowhere, out

of frustration towards their prime minister and telling them how to live their lives. something has snapped in this society, and what is making it worse, and what is astounding is the insults hurled by this prime minister against these young people who really never cared ant politics before and who just want to be heard and feel so -- i'm hearing so people -- they're being pushed to the fringes. >> what i don't understand, how much widespread support do the people in that square have? >> entire neighborhoods at 9:00 at night, and grant it, they are middle class and secular, ring out with the banging of pots and pans every night at 9:00. that's been going on for more than a week. i've never seen behavior like that in turkey. >> let's take a look.

tear gas. fouad ajami is also

he's a tough guy. but toughness ways they never he

before are very frightened. he has a reputation of being

vindictive, coming back and rounding up people for the things they have written and posted and a number of tweeters in the port city, more than 30 were detained and are now starting to face charges for inciting violence over social media, which the prime minister has called a menace to society. >> this is live pictures from istanbul. nick, what are you seeing? what's going on? looks like police moving in? >> reporter: it's hard to tell, anderson, when you see movements of police that simply shift changes. police have been doing very long hours here. whether that marks some new progress on the ground. the focus on clearing this area. but there is still that pocket of protests down the left hand side of the park. it seems to be substantial. it's hard to tell given the distance in the dark down there. police are not moving against them. when we first spoke to you earlier, anderson, you saw the fireworks emanating from that direction. so clearly that's something the police will have to deal with. they want to have control of the perimeter around gezi park before dawn. in about 2 1/2 hours from now.

but we are seeing continued activity in central taksim. bulldozers moving in, collecting debris, removing the barricades. they've still got this issue of protesters. once they push them back, simply return to their original position, no matter how much damage they've done to the barricades with police bulldozers. >> as you said, what happens during daylight hours. stay with us, everyone. our story continues. protesters are in turkey. also back in washington, new reaction in the white house ahead. everybody has different investment objectives,

if you're just joining us, police are cracking down on protesters in central istanbul. in taksim square, bulldozers, armored vehicles, water cannons. this is what what it looked like. you can hear pops of tear gas canisters being fired, stun grenades. the clashes have ebbed and flowed throughout the evening, 18, 19 hours. what began as an environmental protest has grown to a much larger protest against the prime minister. the white house has heard

protesters and police in turkey to restrain from violence. the national security council continues to follow events in turkey with concern. dan, how concerned is the white house? based on what they're seeing in turkey, a key ally? >> they're very concerned. the white house, as you pointed out, have been watching the developments there. they're concerned about the fact that some of these protesters have been targeted, that they have not been given the freedom of protesting with having the freedom of expression there in turkey. so there's concern about that. there's concern about the white house putting out a statement earlier this evening talking to that point. there's this -- turkey is a key ally in the region. very important for this administration, from an economic standpoint, but even beyond that. so the hope is that this can be corrected through dialogue. the white house in a statement

this evening talking about

opinion? >> no, not at all. this is a different political crisis. i want to say something about the statements coming out of the white house. we want peace and order in the states of istanbul and ankura. that's standard, boilerplate. the fundamental point about the relationship between the prime minister and president obama was really laid bare some fortnight ago when the prime minister of turkey came to washington. he came with this hope that he can convince president obama to step into the breach on syria. he wanted president obama to give him cover, because the truth is, in turkey, in turkey,

the policy of the prime minister, the activism towards syria is unpopular. people don't want to be involved in the syrian crisis. so he came to washington in the hope that he would have his back covered by president obama. he got nothing of the sort. he went home, and i think this is really -- it's really about that in terms of u.s.-turkish relations. if he is in trouble on some policies, i think president obama dares a fair measure of the blame. >> ivan watson, what happens at dawn? what happens in the day tomorrow? these protesters are still out there. a lot of people have been injured over the last month or so. thousands have been injured,

some killed. but what happens? >> well, we've seen this cycle before. istanbul was quiet for five, six days in between rounds of violence. people start to go back to work, some of these protesters go back. and then by evening, the violence starts up again. and the clashes start again in the side streets. a very important thing to note,

>> my colleagues in the turkish media are terrified of this government and of this prime minister. they're very afraid of criticizing him. they have been -- their credibility has been hurter the my by this crisis, because there was so little coverage of this, because news channels were showing cooking shows and documentaries about penguins rather than showing what was taking place in the largest city in the country. so not only by putting pressure on the media, he's losing the

legitimacy and credibility of other institutions in turkey. >> our correspondents are still on both sides of that square covering all of the conflict. we'll continue to check in with them. we'll dig deeper into the implications for the u.s.

we're following the remarkable events out of turkey at this hour. it's about 3:41 a.m. in the morning in istanbul. joining me now is fran townsend,

also on the streets nick paton walsh who has been with us for 18 hours. nick, give us a quick update on where things are in the square. >> reporter: sure, anderson. to continue cleanup there, you can see some of the people trying to clean away the debris there. one important development here on the road closest to me here, we have seen police moving in, using tear gas, water cannons to push protesters back. the police have moved on, and we have seen protesters back up the road. a bit of energy left in the protests. i've been watching this now for 20 hours. they really aren't letting up. it's going to be difficult for police to dislodge them on that road closest to me, anderson. >> fran, we had professor fouad ajami on a short time ago,

critical of the obama administration saying they're watching this with concern is sort of boilerplate. this is a key ally for the united states in this region. >> that's right. prime minister erdogan is at a critical moment. the administration has to signal to turkey they're watching. but at this moment, erdogan, if he oversteps his bounds, the administration has to leave itself some room here. ivan said something important here. the notion that prime minister erdogan is referring to these protester as terrorists means something. it means something to the security forces because of how brutally they deal with the kurdish movement and the terrorist movement there, and they're willingness to use force. remember that erdogan has had an uneven relationship with his security forces. the question is how long as we've seen in other countries, how long will the security forces support the prime minister in this effort against

the protesters and how brutal are they willing to become with them. we're seeing tear gas and water guns, but there's a real potential for escalation here. >> and, again, you can't underestimate how volatile this region is right now with syria and what's happening in northern lebanon and elsewhere. >> that's right. erdogan is facing something of a political fight, as you heard fouad ajami talk about, the prime minister's concerns that he would have expressed to president obama during his visit. he didn't get the kind of support. we're seeing an escalating crisis in syria, and so that puts the prime minister really in a difficult position domestically. i'm not sure americans really appreciate, this is a domestic political situation that is playing out that has international ramifications because of the strength of this nato ally. >> it is interesting to see how this has gone from a protest over a park in taking down of

trees and putting up development in their park area, into voicing of frustrations with the leadership, voicing frustrations with the style of rule, though he has been democratically elected and it's his third term. >> that's right. we see whether it's american presidents -- when you're re-elected and second term presidents make many controversial appointments because they don't have to face reelection. prime minister erdogan is a tough guy. you've heard him described as being notoriously tough. i don't think it's in his political interest to allow this to continue the way it is. he ought to be looking for a way out and a way to take the passion out of this thing and reduce the violence. >> fran, appreciate you being with us. we'll continue updating throughout the evening on this

story. also, late word on the edward snowden leak investigation. what he could be facing if and when he's found and what kind of charges a leading lawmaker says reporters should face for helping him. woman: everyone in the nicu -- all the nurses wanted to watch him when he was there 118 days. everything that you thought was important to you

the program that "snatches every american's address book." each denies providing the government direct access to their servers. snowden's girlfriend says she is, in her words, adrift in a sea of chaos. lindsey mills is her name. she describes herself as a pole dancing superhero, saying my whole world has opened and closed at once, leaving me lost at sea without a compass. there are already briefings in washington, charges being considered. let's get the latest from miguel marquez in hawaii. what is the latest? >> reporter: we know there were two police officers, two law enforcement officials that went to his house last wednesday.

we do know that one of them was a federal official. but it does not sound at this point that they knew that snowden was the leaker at that point. two things happening at that point. they knew snowden was missing and somebody had leaked documents because "the washington post" and the guardian had gone to the feds prior to publication of those documents speaking some response from them, so they were -- that link had not been made between snowden going missing and those documents being leaked. >> have they gone through his belongings or had he taken them out of his house? >> reporter: that is a huge question. his house was packed. his garage at least was packed to the very ceiling with boxes, say neighbors. all of that disappeared, including his girlfriend. cnn did speak to her father a short time ago who says she's holding up, says that snowden is a deep believer and a very good guy and sends him his love, as well. but all of those belongings have gone somewhere, to a storage

facility here perhaps or perhaps back home. but it's not clear that a warrant has been served on them. >> and the guardian reported that his girlfriend was completely in the dark about his activities. >> reporter: yes. he apparently has his computers, his hard drives, all that information that the feds want to get their hands on, all of that appears to be wherever he is right now. >> miguel marquez, thank you very much. the beach looks very nice. house members not a closed door briefing today. they take up the affair on thursday. battle lines are being drawn. senator ron wyden of oregon calling for hearings, saying the american people, in his words, have a right to expect straight answers from the intelligence leadership and doesn't think they're getting them now. dianne feinstein continues to defend the programs as necessary and proper. both she and john boehner calling edward snowden a

traitor. so does congressman peter king, who chairs the house subcommittee on counterintelligence and terrorism. your colleague called this guy snowden a traitor. do you think that's true? do you think he's a traitor? >> i think he's either a defector or a traitor, take your pick. what he's done will put american lives at risk. i don't know how he can live with himself. so traitor is as good as term as any. i think he's violated the espionage act. >> can you say specifically how he has damaged national security or put the lives of americans at risk? in the wake of the wiki leaks revelations a couple years ago, there were allegations made, and then months down the road, you know, the secretary of defense came forward and said the damage, it was embarrassing, but there wasn't the level of damage that we had thought. what specifically do you think

has harmed national security with these nsa revelations? >> al qaeda and allies now know with great exactitude of what we're doing and how we're doing it. they monitor everything we do. they could not have been aware of a number of the details that come out. that to me is putting american lives at risk. just on this alone by giving the enemy such detail about what we are doing, that enables them to adjust their strategies and tactics and that is very damaging to america. >> as far as reporters who helped reveal these programs, do you believe that something should happen to them. should they be punished, as well? >> actually, if they willingly knew that this was classified information, action should be taken, especially on something of this magnitude. i know the whole issue of leaks has been gone into, but something of this magnitude,

there is an obligation both moral and legal, i believe, against a reporter disclosing something which would so severely compromise national security. as a practical matter, i guess there have been a number of reporters who have been prosecuted under it. so the answer is yes to your question. >> i want to play a quick exchange between senator ron wyden an james clapper. i want to play that. >> does the nsa collect any type of data at all on millions or hundreds of millions of americans? >> no, sir. >> it does not? >> not wittingly. >> do you -- is that a factual statement as far as you're concerned? >> let me just say i think director clapper was in an unwinnable position there. no matter what he said, he would have compromised national security.

anderson, this is like asking someone on june 4 or june 5, 1944, are we planning d-day in two days? my understanding is that the senator asking that question knew what the answer was. when you're asked something in public about something which is so classified and so sensitive, it really put director clapper in an unwinnable position. untenable almost. >> congressman peter king, appreciate your time. we'll be right back with more from the latest from turkey. and for the last four summers, coca-cola has asked america to choose its favorite park through our coca-cola parks contest. winning parks can receive a grant of up to $100,000. part of our goal to inspire more than three million people
