we meet the armed vigilante's in burundi who say they're protecting their neighborhoods from random attacks. this is al jazeera live from doha. also ahead on the program. >> we are now investigating these horrific acts as an act of terrorism the f.b.i. however says there no evidence that the couple behind the mass shooting in california were instructed by i.s.i.l. raising the alarm, the u.n. says half of yemen is one step away

from fam ine. thousands of south koreans take to the streets of seoul against anti government protests. three gunmen dressed in police uniforms have been killed in burundi's capital. it is the latest incident in the african nation hit by violence over the president's third term. the government says it's fighting insurgence. catherine soi talks to some of the men who say they're just protecting their neighborhood. >> reporter: when the sun sets, work begins in a suburb of burundi's capital bujumbura. piere and others say they're protecting their homes from

security forces and members of the ruling political party youth wing, which they blame for the recent spate of random and regular killings in the city. they will defend themselves, this man says. a little earlier we met two young men. they dress like police and dig out a grenade. he says they will use this today. they p wouldn't say where they get their weapons from. >> translation: police have been coming to our neighborhood to arrest and kill us, but at night we go to where they are and fight them. >> reporter: what started as peaceful protests in april against the bid for a third term by the president has evolved into armed violence. people are being killed almost every night and bodies left in streets or in trenches. the government and opposition

factions blame each other. >> the protests, they found another way. they tried to negotiate with the government, but you cannot negotiate with government when you are committing homicides like this one. >> reporter: the united nations african union and human rights groups are concerned about the killings which they all say have an ethnic dimension to them. it's a disturbing trend for those who follow burundi affairs closely, such as this lady. there were also killings following the 2010 presidential election but more people now seem to have weapons >> if they would decide to combine forces, the vigilane and the more organised armed groups, we could find a rebellion that is much more dangerous and

sophisticated and they could gather more resources to challenge the state. >> reporter: the armed men told us they won't give us until the president steps down. government forces insist that they will hand down each one of them. many innocent people are caught in the middle the f.b.i. is investigating the mass shooting in the u.s. state of california as an act of terrorism. there are reports that the female shooter pledged allegiance to i.s.i.l. on facebook. the agency says it is unlikely the couple were directed or ordered by i.s.i.l. to carry out this attack. reporting from san bernardino. >> reporter: a dramatic turn of events just 48 hours after a mass shooting that killed 14 people investigators now saying it's a terrorism investigation. >> based on the information and the facts as we know them, we are now investigating these horrific acts as an act of

terrorism. we have uncovered evidence that has led us to learn of extensive planning. obviously, we've uncovered evidence of explosives. >> reporter: the first picture of tashfeen malik, the 27-year-old investigators say was the second shooter. the f.b.i. saying a number of pieces of evidence have informed their decision on terrorism, but offered few further details of what that evidence is. the investigation is now likely to increase its scope and urgency. despite ram pant speculation in the u.s. news media there was no evidence released by the f.b.i. that i.s.i.l. directed the attacks carried out by tashfeen malik and syed farook. it is a complex case and neither of the two suspects appeared to be on any f.b.i. watch list and nerth are criminal records in america. the f.b.i. urged patience, saying it might take a long time

to get to the real motive. >> there's a lot of evidence in this case that doesn't make sense and so we're trying to be very thoughtful to understand it and to make sense of it, so we understand the full extent of what we have here. >> reporter: officials did say they don't think this was part of any larger plot, but that will likely do little too ease the fears here the lawyers representing the suspect family say the media is paying too much attention to their religious background. >> there was information about the fact that his co-workers kind of made fun of him, for example, and his beard. he was a very isolated intro verted individual with really no friends that we could identify, like maybe one friend or no friends. i guess what we would say is that when an incident happens like this, when a christian goes

to shoot up a planned apparenthood or an extreme catholic goes and bombs an abortion clinic, all the headlines don't say extremist radical christian, catholic, christian, just like right now every headline is saying muslim and attaching muslim to it. i think there's a tendency to take a cooker cutter paradigm of a terrorist event and impose it on a situation because that person is a muslim. the chief has come out and said that they have found no link to largeer terrorist group or terrorist cell, i think people need to listen to that and consider that. every headline, until there is absolute clear evidence, every headline doesn't have to say "muslim massacre", or "muslim shooters" iraq's prime minister is

demanding the immediate withdrawal of the turkey troops. turkey has deployed several hundreds soldiers to the sit of mosul that is under turkey control. a training mission has been there since last year. imran khan. do we know what is exactly going on? >> reporter: i can confirm to you that ankara said a number of troops have crossed over from turkey into the province on the outskirts of mosul. the problem seems to be is these troops have crossed over on the vision of the governor. he runs a militia up in that region which is regional national motor bike iliceation-- mobilization front. this caused a row between the two countries.

they have been arguing over oil revenues from the kurdish region. they have also been very angry that there are these trainers who have been invited by the kurdish and the sunnis that are living up in the north and seemingly ignoring. what one source has told me that is close to the mobilization front is that it is not this idea that you can have iranian backed militias fighting against i.s.i.l. and that's okay, baghdad are happy with that, but the minute we ask people to come and help us in our fight against i.s.i.l. forces up in mosul, then that seems to be a problem. the prime minister has says that he doesn't want any foreign boots on the ground here. he said the iraqi security forces can deal with i.s.i.l. themselves. that hasn't really translated when it comes to mosul and the government of mosul is saying to baghdad, we need more help and if the turks are happy to give it to us, i'm happy to take that help

what is the commissioner for human rights are saying about the sunnis and northern iraq suffering a back lash. what can you tell us about that? >> reporter: you will see that two weeks ago the iraqis mounted a very successful operation backed by the u.s. state coalition air strikes on sinjar mountain. the mountain was cut off, two areas cut off. it was taken over the kurdish peshmerga forces and it was seen as a key excuse against i.s.i.l. what has happened is sunni arab families are stunned between the areas that peshmerga control and i.s.i.l. they're in no man's land. i've been followed who have access and knowledge of those people living in the area that the occur dish peshmerga and the krg government here see them as being collaborators with i.s.i.l., they were there with i.s.i.l. siting the kurdish peshmerga forces so they can't cross back. those families say if they go back towards the identify lines

they will be killed by i.s.i.l. fighters and they're in no man's land at the moment. there are negotiations going on to get them out. there are two main tribes in the area. they're trying to bring them together to get them safe passage. i'm told there may well be a solution coming, but this has been two weeks now where these families have been stuck and there's at least 213 families stuck up there. that might be at least a thousand people that are stuck in this no man's land. this keeps happening in places where sunnis have been trapped between i.s.i.l. forces and kurdish peshmergas families - families should should say. u.n. hkr have now commend on it now and that's why thank you. the u.n.'s world food program says yemen is at risk of flipping too fam ine. it is now classified being on an emergency level of food and

security. the world food says over 14 million job people with struggling to get enough food because of the world. more than a you a million people have been sdlafd. >> reporter: yemen is one of the hardest places to work. massive security concerns, escalation in fighting and violence. we are improving our reach and getting to more people every month, but clearly with half the country now one step away from fam ine, we need the community to get behind us and support us over the next few months thousands of people are protesting in south korea's capital about government policies. a court through out having a rally banned. these are live pictures there. our correspondent is joining us live. it was just three weeks ago that south korea saw one of the largest protests in nearly a

decade. clearly the crowd is huge here as well. a second protest. tell us more about what they're upset about. >> reporter: one of the things they're upset about is government reaction to their protest a few weeks ago. it got quite violent, water cannons were used. one of the person who was at that protest is at that hospital. protesters are coming out to protest not just that but the issues that they felt were overshadowed back then by the violence that broke out. those issues, labor reformss that workers feel is favoring big corporations as opposed to the laborers, as well as a government policy now to basically issue a state authored history book and do away with all the other history books that are currently being used by the schools. so many here are frustrated at what they see as a rather

authorityian still. they're frustrated over economic realities as well. the opposition is using this to rile up anti-government sentiment, but there is much more going on here than just anger at the government. it's really down to frustrations of what the ordinary civilians see as a win here by a very small minority over the economic policies of the country. they feel the labourors are being left behind and they want that to change they seem focused given this is the second protest. what is the mood now, since the last one turned violent? >> reporter: it's much more subdued. there are an estimated 30,000 people here, so less. they see it as a minor victory

that the police is off the street. there is a notable lack of police here and they think that has contributed to a deescalation calation. they are planning a march here. this protest is expected to go on for another few hours, but it has so far been peaceful and the protesters say they intend to keep it that way thank you for that, live from seoul. coming up in the program, brazil's president goes on the attack against impeachment proceedings as she fights for her political life. plus we're on the front line of climate change who are finding their livelihood washed away. sure, tv has evolved over the years.

it's gotten squarer. brighter. bigger. it's gotten thinner. even curvier. but what's next? for all binge watchers. movie geeks. sports freaks. x1 from xfinity will change the way you experience tv.

>> half a million fields will lie fallow.

>> if we had another year of this severe drought, i'd say all bets are off. top stories now on al jazeera. one of the groups on neighborhood watch in burundi's capital says al jazeera america it won't give up until the president steps down. the country has been plagued for violence for months. the f.b.i. is investigating the mass shooting in california as an act of terrorism. there are reports that the female shooter pledged allegiance to i.s.i.l. on facebook. the agency says it is unlikely that the couple were instructed to carry out the attacks by the group. thousands of people are

protesting in south korea capital over a series of controversial government policies. a court threw out a police attempt to have the rally banned after violence in a similar demonstration last month. venezuelas will choose a new assembly on sunday. a recession and a soring inflays rate has boosted the opposition's chances of winning its first majority for 16 years. there is growing concern over the integrity of venezuela's voting system. >> reporter: at a community city in car carakrs mothers scramble to get caps. just ahead of the arrival of one of its top con aggressional candidates. this woman ashores us that the

voting system is tamper proof. >> translation: the system has been audited and will reflect the true will of the people after they go to the polls on sunday. >> reporter: indeed, this time around even the opposition coalition says it's satisfied venezuela's electronic voting system gives sufficient guarantees. but is that enough? it's not the actual voting process that is raising red flags but everything leading up to it. the top of the list is the use and abuse of states resources to tip in favor of the ruling party candidates. the socialist candidate is distributing a government subsidy benefit to young mothers who are being reminded that it's their duty to defend the revolution with their vote. the government overwhelmingly controls venezuelan's television networks, bombarding the airways with propaganda against the opposition.

ngos monitoring the campaign are also concerned the voters could be pressured at the polls. >> translation: i'm not sure that people will have to the freedom to cast their vote properly, that when they go up to the machine there won't be someone watching how they vote, that they won't be afraid of losing their jobs if they don't vote the way they're supposed to. >> reporter: the president of the elector alcouncil is considered a government loyalist and for the first time no international objector groups have-- observer groups have been accredited except one >> translation: we have a double responsibility which is why we are appealing for a peaceful nonviolent election and secondly, that all players commit to recognising and respecting the results of the vote. >> reporter: with so much at stake, the stability of the deeply divided nation will almost certainly depend on it brazilina president dell has

strained the impeachment against her is false. >> translation: i will fight this impeachment process because i have done nothing, nothing that justifies this procedure and primarily because i have a commitment to the people of this country who elected me besides the political crisis, dell is being blamed for the country's recession. many of her grass root supporters are turning against her. >> reporter: this man and his wife say they're struggling to make ends meet. they live in on the outskirts of brazilia.

>> translation: i think that the previous government was better. it's difficult to sell anything these days. i'm not sure what will happen with the president, but we're worried about other things. >> reporter: his wife has a small beauty salon in the house. they don't support her any more. we're 15 kilometres away from congress and they're not worried about the impeachment process of rousseff, but of the economic situation. people say that they feel the contraction of the economy. i am told that in the past shops like this one was booming, but now they're almost empty. it has been a difficult year for the brazilian president. the economy is in recession and there is self-ongoing investigations involving politicians close to her. now there is a political common, people have tone to the street--

taken to the street. we're told that more demonstrations are on the way. >> translation: we are planning to carry out more demonstrations to pressure congress to continue with impeachment and show the politicians that they cannot do the wrong thing. it is not just by congress but by the people >> reporter: analysts here say the president is facing a real challenge >> there's a great resistance or rejection because when a severe political crisis where she cannot govern, she has zero governable ultimately and we're in a very bad economic crisis, going from a se session to the-- recession to a depression. the country is in bad place. if she continue in office she will not be able to get us out of this situation. the cards on the deck on the table are somewhat stacked against her right now. >> reporter: the impeachment process is going to be a long

one, but people like this man say they want it to be over soon for better or worse so that the country's leadership can start focusing on how to get the country's economy going once more breaking news to bring to you coming to us out of lebanon specifically and tripoli. the army conducted a raid on a suspected militant and at the time during this raid reports are that the suspect ended up blowing himself up and that caused the deaths of three people. so during this army raid on the home of a suspected militant, three people were killed. that is what security and medical sources are telling us. we will continue to follow that story for you out of tripoli. a multi national operation has freed 900 hostages held by boko

haram. the hostages, including women and children, were being trained as suicide bombers and fighters. >> reporter: in the back of a packed truck there was relief and desperation, exhaustion too. among women and children fleeing during an operation led by the cameroon military. now in need of food and water. this group were among 900 hostages who had been held by boko haram fighters in different places between cameroon and nigeria. cameroon says a senior member of the group was killed during the two-day operation which also left 100 fighters dead. >> translation: among the enemies neutralized we can count the man known as the head of operations for boko haram in the area. he led several attacks against her territory. large amounts of weapons and

ammunition and flags were confiscated during the operations. >> reporter: boko haram roughly translates as wednesday earn education is forbidden. it's armed campaign in northern nigeria has led thousands deaths. it has aligned with i.s.i.l. yearly in year and has been carrying out several cross-border attacks in cameroon over the past few months. >> it's not quite possible at the moment to put an exact estimate on the amount of fighters on the boko haram side now, but one thing we know for certain is that they obviously lack in manpower at the moment in comparison to the numbers on the side of the multinationalal joint task force. >> reporter: it's unclear whether any of the women and girls freed this week were among the more than 200 sowsd from their dormitoriess more than a

year ago. though freed in this latest operation will now been reunited with their families earlier in the year we visited a fisherman on a shrinking island in bangladesh. climate change has brought rising sea levels in parts of his home which have already sunk below the water. we returned to the island to see how he's coping. >> reporter: after this year's devastating monsoon it's time for this man and his mother to rebuild their lives. he can barely get out of the house in the rainy season much less work. >> translation: it gets really muddy here and i can't see where i'm walking, so i slip and fall all the time. the monsooon is bad for me. >> reporter: the island is disappearing past.

a mosque where we saw people take shelter from storm in may now lies teaterring on the edge of the water. this was one of the strongest monday soons - monsoons people can remember. >> translation: you have the anger of the current. i've never seen the water come with such anger. it would erode away homes before, but this time it just bashed them away. >> reporter: this was the location of his largest ferry dock. it is the main connection to the rest of the country. the landing was swept away by the waves a few months ago leaving an already remote island even more isolated. with no ferry to the mainland, it is difficult for this man to find a job, even though the rainy season is over. it seems there is just not enough going on in the island economy to accommodate those with disabilities. >> translation: we need to get out on the boat, all the way out

on the water and work with nets with others. i can't do the work without my eyes, so the boats don't hire me. >> reporter: after a rainy season like this one, he is worried he has to leave his home once again, but with no heating system on a house on an island where the temperature can drop below 6 degrees celsius, it is hard. and a few contacts the san bernardino killers had in the community, tell "america tonight" what they know. >> educated ignorant people who do those things. he was very educated. >> our investigation from san bernardino and where the trail may lead.
