>> this is al jazeera america, i'm randall pinkston in new york. here are our top stories. the city of brussels remains in lock down as 16 are arrested in connection with the paris attacks. also, taking the war against terror to the internet, the topic of tonight's week ahead. in iran, a washington reporter is sentenced to prison for

spying. his family insists he is innocent. the merger of pharmaceutical giants, the $150 billion deal would be the biggest ever in the industry. >> in belgium, it is low pressure monday morning but the only people on the streets are security forces. everyone else is being told to stay in their homes. the city remains on lock down. earlier tonight, authorities announced they searched does of houses and arrested 16 people. hundreds of police remain out looking for an accomplice to the violence in paris. authorities initiated the highest threat level and say their prime suspect is still at large. >> until now, no firearms or

explosives were found. salah abdeslam was not found. specific elements of the inquiry necessitated the inquiry. >> paul brennan has more from brussels. >> it's been extremely tense for us here in brussels for the past few days, there have been police cordons placed around, all the media of here and you could see essentially what we've done is concentrated down on the main police station there for three hours. not very far. you can see the tower there. that is the town hall of brussels. so we're right in the center, extraordinary state of affairs. but the announcement on sunday

by the prime minister, that the state of alert was going to stay at 4, that the metros were going to be closed on monday, that the schools also are going to stay shut on monday, gives you an indication of just how tense people are here. the authorities are on a high state of alert. they're convinced that there are people such as salah abdeslam and potential accomplices who have weapons and explosives and taking no chance whatsoever. >> paul brennan in brussels. now to france, where the city of sommes had ordered people to be at home at night. but only in an area that is mostly muslim. >> all the raids they've been conducting there one city not far from paris is ending a curfew that's been going on for three days. come 6:00 a.m. on monday this city just about an hour's drive

south of paris will end this curfew that was put in place friday night. this is what a state of emergency looks like. the past week, hundreds of raids have been carried out across france. police are looking for suspects from the paris attacks, and trying to thwart other plots before it's too late. the city of sonnes just an hour from paris. police found false documents and illegal weapons there. many sonnes residents. >> they are ready to be surveyed and to lose a part of their freedom in order to be more sure, more in security. >> reporter: also many of those lives in cham champks pla.

>> there are troops and police on paris's streets but no curfew. under the state of emergency france is dealing with a new reality. one where local authorities can put people under house arrest, conduct warrantless searches and place a whole community under curfew. the government will be able to carry out these powers for the next three months.

sonnes is the first community to impose a curfew but other cities in france could do so, increasing suspicion and division. randall, as you can see, some in that community very concerned that they're always under the looking glass, always being suspected and they fear that could lead to greater division instead of solidarity here in france. >> adam rainey in paris. well, the paris attacks that put americans on unrest. president obama. >> we destroy i.s.i.l. on the battlefield and we will destroy them. we will take back land that they are currently in. we will cut off their financing. we will hunt down their leadership. we will dismantle their networks and their supply lines and we

will ultimately destroy them. >> the president spoke in malaysia where he was wrapping up attendance at regional summits. britain is ready to step up its involvement in the fight with i.s.i.l. prime minister david cameron would reportedly designate 5,000 troops to defeat terrorists inside syria. the official plan is suspected on monday. two brigades that will be deployed without notice. explaining the plan to francois hollande, once back in london cameron will give details to his parliament. mayor bill deblasio says new york city is prepared in the case of a terror attack. the mayor's comments followed a security drill in the city's subway system. hundreds of local and federal agents responded to a simulated active shooter incident.

the drill was performed just before one of the busiest weeks of the year with the macy's thanksgiving day parade on thursday. how i.s.i.l. uses terror and social media to conduct attacks. in the week ahead as french president francois hollande travels to washington. fueling anxiety across the european union, the largest economy germany expecting to welcome refugees, but as karl penhall reports. >> they're clearing ground for a new 350 bed refugee camp. this is an industrial park in

dresden. a city that was ripped by allied bombing in world war ii and became part of communist east germany. 25 years after reunification, the region remains much poorer than western germany. just over a week since the paris attacks and fresh graffiti suggests that some residents don't want more refugees here. hans frank who is getting paid to build the camp doesn't want them either. >> translator: my dad was a russian prisoner of war but he came back to rebuild dresden. syrians could be honest people and rebuild their own country but there is a lot of syrian criminals. the only thing we can learn from them is how to blow ourselves to piece he instead of dying slowly on welfare payments, he says. the paris terror attacks may be

fueling antirefugee sentiment but the city was already home to a radical antimuslim movement called pegida. we should go back and rebuild the berlin wall, i'm a socialist but i do support pegida, i'm not a nazi he says. several refugees are sheltered in this disused building supply store. security is tight. because the facility is already been targeted. by what police describe as neonazis. the regulations on the door are clear. no wine. no weapons. no weed. we joined these refugees as they head to play soccer.

here there's a bit of racism but in other cities like dortman,hamburg or berlin, herists racism he says. this 20-year-old mor 20-year-ol, european intelligence services fear some of the paris attackers, suspected islamic state terrorists. they say they fled after escaping government prisons, seen relatives killed by i.s.i.l. or the syrian government. all were shocked by the paris terror attacks. i'm sad for what happened in france. muslims just do not do things like that.

in the niche suburb of frytow, residents have protested the conversion of a hotel into a migrant hostel. a locally motorcycle club have been vocal opponents. i think we've reached the limit and we need to send half of them home but make no mistake, these refugees will not simply want to go home. among them there will be some like in france or like the ones hiding in belgium and one day they will act, he says. in an area racked by high unemployment, others regard many of the new arrivals as economic migrants pep they blame them for draining the welfare and health system. they should get out of germany. they're scroungers. if one of us does something against the state or the economy or we cheat on taxes we get

taken to court. but the refugees get a free pass. they're allowed to steal groceries and even get a free bus ticket, he says. those disgruntled voices are at odds with the open door policy of the german government. but the terror attacks combined with the refugee crisis could fuel a potentially explosive political mix. randall. >> karl penhall. jason rezaian has been apparently sentenced to prison on a charge of espionage. no information not teen length of the sentence, in a case veiled by secrecy from the beginning. paul beban has more. >> on the website of iranian state tv, the spokesman for iran's judiciary has stated only

that rezaian has been sentenced to prison and the extent, saying, my brother is an innocent man and a well respected journalist. as our family gathers for thanksgiving we are hopeful that jason will soon be reunited with us. rezaian a former tehran bureau chief, because rezaian has done nothing wrong. >> if iran had evidence against jason it would have produced this by now. it wouldn't be dragging out this case this verdict this sentence for many, many months without ever disclosing what it is jason did. >> rezaian and his wife were both arrested in tehran in the middle of the night in 2014. she was later released on bail. and when rezaian was convicted she and rezaian's mother went to

the revolutionary court and tried to learn details but were turned away. he has been held far longer than the american hostages 1979. repeatedly discussed on the sidelines but with no resolution. >> we are working very hard on that. >> we certainly would have hoped that at that juncture at any juncture that iran would have done the right thing, shown its humanitarian concern, released jason since there's nothing against him. >> many feel his case is caught up in internal politics. >> jason was writing about the people, the lifestyle, nothing that would have aroused the sensitivities of the iranian authorities in any way. he's been the victim of forces

in iran between the more moderate and conservative ones. even when the sentence is handed down remains shrouded in secre secrecy. >> litmus test of the political movement in the city. vying for 363 council seats, a vote coming after somehow violent positions. free elections withouted direction from beijing. mauricio maccree's office. >> 12 years they have been waiting for opposition to win and sunday that's exactly whap.

macree, scioli, for over 12 years argentina has been to the center left in very strong presence of the state, between the government and the u.s. based hedge funds that are suing argentina. very close relationship between venezuela and are argentina. sinso this is going to be a radl change for china. to raise currency. be what a lot of people here are waiting for. >> that's teresa vo, reporting from buenos aires. >> the boards of pfizer and

allergan, are merging. could help pfizer lower its american taxes. allergan is headquartered in ireland which has a lower corporate rate. police killed a boy carrying a toy gun a year ago. communities call for action, a live report next. plus a gunman aims his gun at the head of a good samaritan trying to stop a robbery. the gun misfires and the med student survives. survives.

>> at least ten people were hit by gun fire in new orleans. at least 16 folks were taken to area hospitals. they were headed to a park in the 10th ward, one group had walked there after a neighborhood parade. the other was said to be illegally videoing a music show. so far no word of fatalities.

also in new orleans. the shooting of a good samaritan all of it caught on surveillance camera. 21-year-old urick kane who police said, dragged a woman down the street, when a university of tulane stopped to help, he was shot, pulls the trigger twice but the gun jams. the student's friends call him a hero tonight. >> anybody that would do that, is a really upstanding citizen and student. i'm glad to be -- i'm glad to say i went to school with him. >> this is somebody who made a conscious decision to commit harm to this woman, this man stopped to help and we're proud of him being able to do that. >> police say they're confident that they will catch the suspect. peter gold remains hospitalized in critical condition but his family says he is improving.

>> demonstrations marked one year since a police officer shot and killed a 12-year-old boy in cleveland. a candlelight vigil is held today, and as al jazeera america's andy rosean says. it's more about the cleveland incident. >> this raucous demonstration, didn't just focus on tamir rice. it also includes mothers who have lost children in other cities. and a phrase routinely tossed around this weekend by members of the community. police terror. are you worried that that is going to draw people against you? >> i don't think it is going to jaw-drop people against us. i think what's happening is

people are beginning to see what police terror is. you can live in a community in the united states where police are committing terrorististic acts. >> that is a police officer right there in the pews, curtis palmer. there are things that don't bother hymn. >> there are certain things that look bad, that look like terrorizing. you can't change that. if you treat people the way you would want to be treated you wouldn't have the situation we have. >> he was on his way home from visiting a friend. >> andrea never sued never had anyone rally around her cause. legally she just let it go. >> if he had been murdered now i would have had the support. but you know something? those who kill my son will pay for this before they leave this

earth, i promise you that. >> reporter: and she has no problem calling it police terror. >> it is incendiary. because we're at war in this country. >> andy rosegen. al jazeera. >> just one of the concerns when french president hollande visits washington, the topic for this nigh's weet ahead. nigh's week ahead. >> a culture threatened nine days ago. ys ago.

>> welcome back to al jazeera america. here is a look at your top stories. belgium has arrested 16 people around its capital city. hundreds of police searching for accomplice from paris

approximates the city on lock down through monday as leas at . president obama's words come as i.s.i.l. has vowed to stage terror attacks in america. the president spoke in malaysia where he was wrapping up regional summits. in iran, washington post reporter jason rezaian has been apparently sentenced to prison. he and his wife were arrested last year and she was released on bail. it's sunday night and time for our regular look at the week ahead. french president francois hollande will travel to new york and washington this week. looking to stop potential attacks on i.s.i.l, such as the one that killed 130 people in paris just a week ago. the task is becoming more

difficult, using jeefd for everythinsocial media,which hast of i.s.i.l.'s strategy and that the armed group has taken to twitter and facebook to target those who might launch attacks on its behalf. al jazeera's bisi onile-ere has more. >> are this month' >> reporter: this moss attacks in paris, terrorists are using encrypted communications on parts of the dark web, a part of internet not accessible to everyday users. but the open internet is also being increasingly used as a tool to coordinate attacks send funds and instigate propaganda. authorities are following up on

a growing number of threats even ones that appear to be pranks about.iabout. in 2014, a 14-year-old dutch girl tweeted a threat to american airlines. said it was a joke, she was still confronted by authorities. not considering a lack of matter, credible threats from groups like i.s.i.l. and there are many of them. the brookings project on u.s. relations with the islamic world, recently released the twitter census. at least 46,000 twitter accounts were identified that supported i.s.i.l. almost 60% of those accounts were created just last year. to put it in perspective, twitter's user base grew by 20% in 2014, about number of new i.s.i.l. supporter accounts nearly tripled during the same period.

>> we were also surprised the high volume content, 1 to 2,000 users were publishing hundreds of tweets per da tweets per dayg i.s.i.l. content. >> one account posted, imagine the scene while one of the twitter employees is out at a nearby bar, drunk and it's dark? a lion waits and jumps and cuts his throat. >> individuals whose behavior has changed, in the process of radicalized. this digital signature is important to track befor. we can monitor.

>> police say suspect told them he just wanted to rattle students. as more people around the world turn to social media, deciding which threats to investigate could end up being the difference between life and death. >> that's really like finding a nietle ineedle in the haystack. >> reporter: bisi onile-ere, al jazeera, new york. >> author of the naked future what happens in a world that anticipates your every world and from newton, massachusetts, first question to you mr. tucker, there was an internal state memo athat leaked which determined i.s.i.l. is winning the cold war against

u.s., what do you think of that assessment today? it is in line with what a lot of people have been saying, even undersecretary ever defense michael lumpkin, said a lot of the components, in terms of reaching out on social media to combat the i'll message. right now, the think-ash acknowledge social media office that that comes out of is about 65, five of the people in that campaign come from dod. you compare people in the state department whose job it is to have an effect on social media, perhaps 60,000 to 90,000 different people have been countered on twitter a leap, that are able to carry that

message, we began to, they are very limited in terms of what they can say, jihadist or radical sympathizers, can really engage in social media communication. the state department is limited. there is a sense if you talk to a lot of people that there is some lopsided manning here and as big as the effort is to try combat i.s.i.s. >> sorry to interrupt you. let me interrupt you there, our other guest mr. berger has done extensive research on just that area that you're talking about, the methods that i.s.i.s. is able to use and how they're getting their word out. question to you mr. berger, in general terms how important is social media and the ability of i.s.i.l. and its organizations to recruit followers and tell us

something about the sophistication of their work. >> well, the importance of social media really is directly inversely proportional to the distance from tice territory that yoi.s.i.s. territorythat y. if you are in north africa you're much more likely to get recruited on the ground. but when you get into europe or united states or canada then social media becomes very important. their efforts are pretty sophisticated. they use a pretty consistent play book, they use sharp tactics to get around somebody expressing interest to i.s.i.s, their propaganda, they will circle that person, try ocreate a sense of community, and they push themselves from the loam ll

community, the mosque in their area, and they will push them to what some other apps they use to try to encourage them to do something. >> to suggest some people in i.s.i.l. are very well trained with a lot of skills. any idea where that level of sophistication that technical expertise is coming from? where is it based? in the middle east, in europe, where are they? >> the center of gravity is in raqqa syria but the actual people who are doing the work are frequently distribute around the world. so we have seen arrests of people in the united states for instance who are very much involved in this recruitment network. also, there's a very heavy presence of people from indonesia and malaysia in the english language recruitment networks. >> so back to you now mr. tucker. government and private industry as you have written and others constantly monitoring the web

looking for the source of the messages. but here is the question. how in the world are they able to pinpoint the source given that there are millions of messages that flow through the web every day probably. and is it sort of looking like looking for a needle in a haystack? >> well, to a certain extent. so this is the duality of -- the dual problem of trying to complk with peoplcommunicate with peopy are i.s.i.s. you have to engage with new recruits but also have to find some secure way to communicate with potential recruits so you're rail doing both things. this is why you see the popularity of services like twitter but the popularity of encrypted messages like what's app and things like that. there are other aspects of i.s.i.l. that are not

media-savvy too. back in june one i.s.i.s. sympathizer was in syria. they actually put in social media a picture of themselves in front of a particular headquarters for that region. hank carlyle, lieutenant general carlyle of the air force said his team was able to use that to target that facility within 24 hours. this speaks to the duality of the effort, social media and popular open source social media which is to say, the message that i.s.i.s. puts out there freely, this is a great source of intelligence for us. >> let's turn to the slickly produced videos that help i.s.i.l. recruit new members. if the images appear to be familiar there's a good reason for it. let's watch this report from our science and technology expert

jake ward. >> drawn directly from contemporary media. captured a jordanian pilot, later on they go on to execute him, i'm not going to show you that it's too horrible. but in the lead up they do graphics that set up the story, they're quiet familiar. latequite familiar. they are interviewing him and zooming out on these certain maps above hymn. it looks very familiar and that's because you see it all the time for instance in video games. here is 2009's call of duty, it's one in a series of games that's one of the most video game franchises of all time. it's that same effect, the sort of flashing in on the map. it's worth noting that later on in the game you are called upon to basically shoot up an airport, execute civilians a whole crowd of them. you can get through the scene

without doing this but you're certainly given the opportunity to. western media puts out this imagery all the time. the difference is that i.s.i.l. is actually doing this stuff but it's no wonder their propaganda so closely mirrors what we put out in our media. >> that was jacob ward. your twitter services identify some 15,000 i.s.i.l. accounts in a two month period. what does that number tell you about i.s.i.l.'s ability to reach its followers and also to find new followers? >> well, what we know about how social media works and what we really saw in this census, and in subsequent monitoring, is that you can take a relatively small number of people, and make a very big difference on social media. so twitter's user base monthly active user base is about 288 million people. 40,000 is not very much in the scheme of things but when you get into the 40,000, 50,000,

60,000 zone, when you have people work in concert they can make a hashtag trend. they can put their message out on another hashtag that's trending. you know those kinds of numbers allow them to be very effective. what we've seen in the months since that study has been done, is there's a lot of suspensions of accounts, that outreach is limited now, their talking to each other is more of an echo chamber these days. >> i'm wondering if in fact the government officials who are trying to find out who's doing what, is it more beneficial to shut down the accounts or keep them open? >> i think there's a mix. people often talk about this as being all or nothing. we should knock them off the internet, or we shouldn't bother because it's too hard and they'll just come back with new

accounts anyway. my research and common sense say to me there's a middle ground here. at the level they're at now, they find it difficult to achieve the objectives they want to achieve. some of the intelligence has dried up in recent months as they have become more aware of their operational security and the drone strike that was referenced previously. so you know it's not a total gold mine but there is a plot of intelligence that can be had there, i think it's worth managing their activities but their presence there does have operational advantage for us. >> mr. tucker, you have talked about something called doxxing?

>> it is a revelation of personal forecast about someone online by someone who found a record found some document, some bit of personal information about that other person and made it public for everybody. so this is something that the i.s.i.s. cyber-caliphate clt, it is an affiliated support group has done against u.s. service people. it wasn't terribly hard to do, it didn't involve any breach of any fire wall or anything like that, u.s. service people involved in air strikes, regular people like everybody else, they use telephones, they sometimes appear on lists of people that may show up at a certain place or have social media accounts. i.s.i.l. has been able to find that and publish a list of names, a new sort of socially

warfare. an interesting way that we interact with i.s.i.s. in the u.s. military where we also are beginning to understand how to targets individuals which name, a deep understanding of who they are sometimes before a strike happens. because in the 21st century we create all of this daily for all there time and it is incredibl y important. >> redemption seekers, revenge seekers, they are put in the bin for either one of you, is that a fruitful area of enterprise for government officials trying to track them down? >> go ahead. >> one of the things on social

media, twitter is pretty good, forcing into 140 character format and a limited number of interactions. you are able to go in and kind of create types of inter-actors. i wouldn't necessarily say you could find that on social media but you could find recruiters, people who are trolls, people who are disseminators of information and operational planners. so the bem jan sleeper abd ham d abaod. >> thank you gentlemen very much for shedding light on some very complicated but important era in the new era of warfare. thank you for joining us.

and here's look at some of the other events coming up in the week ahead. as we mentioned, french president francois hollande will be in washington on tuesday and meet with powm. in belgium, the church of scientology could be banned from that country, if it's found guilty of charges including fraud. threat of i.s.i.l. and the recent violence between palestinians around israelpales. environmental issue mounding. >> the snow may be ending blut we are looking at other barts of the country. michigan, snow up to 17 inches in some spots.

and cold air is moving down to the south where warnings are in effect for monday morning. ft

>> a toxic mud flow of mining waste in brazil is now reached the atlantic ocean, it's been flowing downstream since storage dams burst earlier this month. concerns are being raised about the long term environmental impact.

>> fernando gomez has again fishing here for more than 18 years but not any more. millions of cubic meters of mud carrying heavy minerals, mining waste toxic for humans and deadly for all the fauna. >> we're not able to save them. >> aa dam exploded in the town of mariana, two weeks ago. the waste polluted most of the 800 cloment long river. environmentaliskilometer long r. cleaning it up will be a challenge. >> it's a catastrophe that's been underestimated. waste has contaminated the river banks. those deposits will emerge from the siel during the rain judge t

contaminating again and again. >> paying more than $250 million for damages to begin with. the river was the source of water and fish for thousands of people. the army has been deployed to distribute fresh water. the fines will also help finance the project arc of noah, implemented as an emergency measure. fishermen help individuals to create a genetic bank and save them from disappearing. >> translator: we will bring permitspecialists.

until we can return them. >> all the fish are dead. how can we live 00 like this? we are fishermen. all we can do is fishing. they need to give us assistance. >> environmentalists say it will take up to 50 years to reverse the damage. now the contamination has reached the ocean. plenmarinea sarnmarinea sanchez. al jazeera. >> 11 inches of snow, that is the biggest november storm to hit the region in 120 years. this weekend nearly 500 flights were cancelled because of the snow at o'hare international. shoveling in southern wisconsin where 20 inches of snow fell. those individuals, not this kid, they had a blast. quite a storm with snow fall

stretching from south carolina to michigan. kevin corriveau has more. >> we're looking for a big improvement across much of the northern plains and also the great lakes with where that system pushed through. we're still dealing with a little bit of snow but nothing like we have seen earlier across michigan, wisconsin, iowa. this is the most recent video where we had coming out of michigan, 17 inches of wet snow across the region. problems on the highways but we saw trees down, we saw power lines down as well across that area. it's going to take a couple of days for them to start to dig out of that region. now down towards the south that same system has brought a lot of snow from texas to parts of florida. we are talking about freeze warning where as we go into monday morning those temperatures are going to drop down to about 28° in the morning there. you can see dallas is going to

be 36, jackson, mississippi, 28°. dallas, things are going to get better, thanksgiving day we do expect to see thunderstorms in play. on wednesday we're going to be seeing some rain here across the midsection of states but it is going to be quite snowy in the west. on thanksgiving it is going to be extremely messy great lakes to texas and if it is going to be a ski thanks, parts of wyoming you are going to be seeing plenty of snow. >> thank you, kevin corriveau. >> tourists travel miles to sit in paris. and the recent attacks are not going to stop it. >> we love going out drinking, we're not going to stop it, this is freedom. >> a city determined to preserve

its traditions. next.

>> when gufn me gunmen attack restaurants in paris, parisians are determined okeep their image

he employs 28 people and buys from local farmers. >> we have less people to serve. less money coming in and all of that is going to be affected. >> tonight we visited a bar that sits across the street from one of the restaurants that was attacked on friday. the owner was promoting the bistro campaign, his regulars were back too, a nearly full house. it is important for owner of the restaurant to have it full of people, full of life, because just four days ago, a block away at the belle equippe were shot dead having dinner. >> such grizzly scene stechtions away. prepared to make sure that doesn't happen. adam rainey, al jazeera, paris. >> thank you for joining us. i'm randall pinkston in new

york. step up for third rail coming up next. and keep up with the latest on aljazeera.com. today the attacks in paris launch a debate over refugees coming to america. what is the u.s. doing to stop violent extremism already here. in our panel hiv isn't the death sentence it used to be, but are more people becoming infected because the government dropped the ball? my final thought have we already forgotten
