>> isil says this is the bomb it used to bring down a russian passenger plane over egypt. >> hello, i'm maryam nemazee. you're watching al jazeera live from london. also coming up. [ explosions ] >> the paris prosecutor said that the early morning raid was ready to act. a day after the bomb attack killed 32 in the my year january cit--nigerian city two female

suicide-bombers attack. >> the islamic state in iraq and the levant has published an image of the improvised bomb it said brought down a russian airliner over egypt killing all 224 people on board. in the latest issue of its english language magazine the group said it smuggled the explosive on the plane which was destined to st. petersburg after discovering lack security at the sharm el sheikh airport. isil also said tha in the magazine that it has killed one norwegian and one chinese man it has been holding hostage. thank you for speaking to us. >> you're welcome. >> what are your thoughts.

is this the device lined the plane crash? >> it certainly looks like a viable device. but there a number of anomalies with it. the image that you were showing, on the right-hand side is the brains of the bomb, the firing switches, the power source, in the center of the image was the detonator which suggests the explosive, and the can on the left-hand side i saw in iraq once, which contain 200 to 300 grams of high explosives. placed in the right position it could destroy an aircraft. >> when you look at the picture, three such simple components, how--is the simplicity of quite worrying? >> it's quite typical. in any bomb there is a power source, an initiator, power source and the explosive. what is worry something that normal airport security, the metal detecters and the x-ray

machines definitely would be able to pick this up. if it went into the holes and by passed those checks if surrounded by luggage. >> it wouldn't have been a strong or powerful. >> someone would need to know exactly where to place it, which means it could be an inside job, actually. >> that was going to be my next question. what does this suggest, then, about how this device would have been brought on board the plane? >> well, first and foremost it suggests that someone must have been complicit in getting it on board either overlooking the security carried on as hand luggage, or if it went in hold luggage it was put in place in position by one of the staff. the point that it is a russian aircraft, and it tied in straight in on the russian airstrikes on the isis positions, it's quite interesting because even if it was a suicide-bomb, when we see these devices detonating in syria and iraq against isis they

hardly make the news. but when they hit an iconic western target or in this case a russian target there is much more value in terms of its terror effect. >> what would you say is the big take away here for you here? is it the technical knowledge and expertise when it comes to putting a device like this together or should the focus be more on how this device was brought on board the plane, and is that something that they can ever figure out? >> i think its both. it's a technically advanced device you could have gotten something more crude through, but the other area that we have to focus on is the security and the fact that

>> i called the police. they said, no, stay safe at home. there is police action in the city. >> the scale of the operation was huge.

it ended up after seven hours of a motorcade of police special forces speeding out leaving behind the chilling prospects that this could have been a previously unknown isil cell planning another attack. as people return for their homes there are more questions about the effectiveness of intelligence and whether there could be plans for more attacks. andrew simmons, al jazeera, paris. >> we're live in paris. mohammed, developments over the past hour? >> yes, maryam. we heard quite a loud boom from an area today. we're told those are controlled explosions. we heard two more in the last 15 minutes. we're told they're controlled explosions. that the swat teams, the forensic investigators who are still on the scene, they're

finding explosive devices, possibly grenades that were left behind, and they are just trying to make sure there is no more danger, that they're setting them off. we might hear more in the next hours as well essentially what is happening as soon as they find these explosive materials they're detonating to make sure that it does not cause a problem for the rest of the people here. the mood has gotten quite more relaxed in the last few hours. the french media has been reporting that perhaps police are looking for a car that one of the main suspects to the attacks left this area in, so there is still that seven that is ongoing. but as far as the area at this hour the crowd is still worried about what might happen further on. as of now it is more relaxed. more people are coming out and assessing what is going on. there is investigativ

investigative detonators. >> yet so much uncertainty still surrounding who is actually in custody. >> it goes to show how much is left. even after hours of this raid today. the parish prosecutor came out and said look, this investigation is still really going on right now. the main details that he gave us in the last hour were that there were eight suspects that were arrested, seven of them were men. one of them is a woman. there have been conflicting reports. some reports earlier today suggesting that two people were killed in these attacks. others report saying perhaps there were three. and perhaps there is another body found under the republic in one of those apartments. one of the things that the prosecutor did confirm was that neither of the main subjects

were in custody. that they were still being sought after at this hour. and again the prosecutor did go to great links to praise the work of the s.w.a.t. team, saying they put themselves in great danger, and there was a very difficult few hours as many as 5,000 bullets from extended by the members of the swat teams that were here conducting this raid, and again just trying to say that officials are going to go to great lengths to make sure that every suspect is caught, found, and brought to justice. they had found a witness that they had interrogated and got information about this apartment building. but we're waiting for more details and we suspect that more already released in the days after that. >> in paris, thank you very much. well, earlier on belgium gathered to hold a vigil for the victims of the attacks.

candles were lit as people paid tribute to the 129 victims. we've been following the attacks as the police carry out earlier raids looking for suspects. perhaps has carried out a third night of airstrikes in syria. they targeted the command center in northern syria. france said that it would continue air raids in the coming days. now france's only aircraft carrier has left the country to join anti-isil operations in the eastern mediterranean on wednesday. the vessel carries 20 aircraft allowing france to increase the number of raids its staging against isil targets. meanwhile, the united states has released dramatic pictures against isil controlled oil infrastructure in northeastern

syria. it said that more than 100 trucks were destroyed in monday's campaign. more to come for you on al jazeera this half hour. in the wake of the paris attacks we look at a new wave of technology that could raise alerts when threats arrive. plus. the world remembers one of rugby's greatest-ever players.

i just had a horrible nightmare. my company's entire network went down, and i was home in bed, unaware. but that would never happen. comcast business monitors my company's network 24 hours a day and calls and e-mails me if something, like this scary storm, takes it offline. so i can rest easy. what. you don't have a desk bed? don't be left in the dark. get proactive alerts 24/7. comcast business.

a recap of your top stories. the islamic state in iraq and the levant published an image that it says is the improvised bomb that brought down the russian airliner killing all 124 people on board. the french prosecutor said that a terrorist cell ready to attack was neutralized. the raid left two people dead and eight arrested. leaders around the world are looking how they can better protect their citizens. one option is an increased use of smart systems. networks of sensors and cameras that upon for people raising alerts when threats arise. we go to barcelona where experts gather to discuss the new technology. >> a ripple of gunfire identified by roof-top sensors

sent to the police. >> this is the accumulation of gunfire over the past 30 days. >> along with the precise details of the location of the shooting. the technologies used in 90 cities mostly in the u.s. part of an effort to combat gun crime. european cities are considering how it can help them respond to threats in much the same way a fire alarm works. >> here's the value, clearly they're engaged in gun play here, testing this weapon out here. >> the particular case of the paris attacks our technology could effectively do that fire alarm from gunshots enabling law enforcement to get there one minute, two minute sooner and mitigate the down stream consequences of ongoing engagement of active shooters. >> coupled with software, sensors and cameras to track people's movements either in

vehicles or in this example when someone is seen leaving a package on a rooftop. sensors are fast becoming the tool of choice in cities. but they come with a tradeoff. they have to ensure that any loss of privacy is offset by the city becoming a safer place to live. for some that balance has not been achieved with cities too quick to install new technology and yet to see useful results. >> we focus so much on mass surveillance just justice putting everyone in surveillance. in the end we'll have very expensive lots of data that is not necessary or needed. for people who are completely law abiding there is no need. but then we take the money out of the traditional techniques that would have identified u individual persons.

>> making sure that the data is analyzed is a major challenge. al jazeera, barcelona. >> nigerian police say two female suicide-bombers have blown themselves up in a mobile phone market in northern nigeria killing 15 people. it happened in kano and comes less than 24 hours after the attack of an fruit and vegetable market killed 22 people. we have reports now from abuja. >> the attacker is looking to cause maximum damage. most of the victims were young men and women. >> we went to eat. after eating we sat with some tea. in the blast. three of my friends were killed.

hoppeds here are struggling with the injured. although no one has claimed responsibility the attack are similar to those carried out by boko haram. the last being an attack just a few kilometers from here. dozens were killed. countries step up the operations but what they fail to do is to stop the deadly attacks on soft targets like markets. in this year alone hundreds have been killed in such attacks. there are warnings that suicide attacks will increase al jazeera, abuja, nigeria. >> nigeria's president has ordered the arrest of a former national security adviser who is accused of stealing billion dollars which was intended to be used in the fight against boko

haram. allegedly he funneled money into bogus contracts ammunition and aircraft. the president's office said that he wanted $140 million to go transferred to accounts in the u.s. and elsewhere. now u.s. president barack obama has put pressure on china to stop building in the south china seas during the apex summit. but president xi jinping said he would not discuss it during the forum. 19 other economies were in manila for the annual summit where the trans-pacific partnership deal high on the agenda. isil has said it has beheade----

>> a woman kidnapped at the same time has been released. >> two were kidnapped earlier this year. and there was efforts being done to basically rescue them. we managed to get one hostage out. but in this case we were unfortunately unable to retrieve the other one. >> the u.n. investigators say they found a secret underground detention center used for post-war interrogation and torture in sri lanka. the country's navy is denying such center ever existed. they're looking for a huge number of people who disappeared after the war. we have reports from colombo. >> another day, another opportunity to try to find out what happened to their loved ones. photographs held up by families of the missing greeted the u.n. working group on their visit in

northwest sri lanka. >> we want our children, our husbands, our relatives back. it is our loved ones that we need. >> the families more than 21,000 complaints have been registered with the commission of disappearances set up in august of 2013. the complaints are from people, mostly tamil, who went missing during the war. hope is all that is left for the thousands of families who have disappeared and still missing here in sri lanka having exhausted all local channels. they hope the u.n. working group can bring some answers. >> the working group told reporters it was given access to a former detention center ran by the sri lankan navy base.

>> we visited the place where interrogation and torture took place. >> another military camp was where political were abducted almost six years ago. the wife said his hard-hitting cartoons made him a target for the previous government. a group of military officers are being investigated for their role. >> clearly it had to be a powerful person of the regime who issued the orders to them. exposing that person is what i'm trying to do. >> while conceding there was some positive development, they say justice has not been done for families, and the culture of impunity must change. >> the rights of families of those who have disappeared have not been fulfilled by the state. there is a cultural pattern of impunity for cases of disappearances.

that needs to change and be overcome. >> the group will present its report to the human rights council next year. for thousands of families the waiting continues. al jazeera, colombo. >> the riot police have fired tear gas against kraus. unrest in kosovo's relationship with its former ruler serbia is now into its second day. the protesters throwing stones and molotov cocktails at police. opposition law make whose are against the accord with serbia repeatedly disrupted parliament and fired pepper spray inside the chamber. three germany pack backers died in their car. another man understood to be a local farmer was found dead

inside his vehicle. the bush fires are thought to have been sparked by lightening. strong winds are hampering efforts to bring them under control. now described as rugby as first global super. jonah lomu died from kidney disease. he was waiting for a third transplant. he was the youngest ever all black when he made his debut in 1994 at the age of 19. he scored seven tries in the world cup. tributes have been flowing in from politicians, teammates and the public. >> i'm pretty devastated. obviously for us, there are those who knew him well, but also for the family, for the man himself, and our thoughts and our prayers go out to them. >> he just had a real affection for the new zealand people. he was proud of them.

and his happiest moment was when he pulled on the all black jersey. someone who knew his heritage and history and culture. his playing days was dedicated to raising money for academies set up around the world. >> now in the united states leaving a tip in a restaurant is more than showing appreciation for good service. gratuity makes up a significant part of waiters' and pat and waitresses' income. >> a restaurant specializing in fancy vegetarian cuisine. while customers may come here for the unique dishes by law the chefs can't share in the wait staff tips. low kitchen pay was making it hard for the owner amanda colin to find and keep good chefs

until she decided to do away with tipping all together. >> the only way to keep a cook is to pay them more. the front of house made a lot of money, but they were helped by the back of help staff. >> the restaurant now charges 20% administrative fee in place of a tip. it's extra money going towards salaries, wait staff may make less money than they used to at $25 an hour, but they like having a predictable income. >> the biggest difference is thats consistent every single day. which is nice that you can count on that. >> profit sharing plan helps to sweeten the deal. >> the restaurant dirt candy is one of the first in new york to do away with tipping but other restaurant are now following suit. this change comes in a nationwide push to increase the federal minimum wage for fast food workers from its current $7.25 an hour to $.15.

but tip workers make $2.13 an hour. >> while servers in big fancy restaurant can pocket hundreds of dollars a shift in tips the restaurant opportunity center said that the average is less than $9 an hour. >> to have the tip disappear and have a minimum wage like everyone else, if you go anywhere in the country, servers, you don't tip. >> danny meyer recently announced a no tipping policy at his 13 restaurant. but the national restaurant association said that most restaurant are worried about raising prices even though customers at dirt candy found it easier to have the tip incorporated into the bill. >> i think if takes a lot of pressure off the customers. and i think it's a way of the future. it's going to be good. >> still it may take a while before other restaurant decide to take tipping off the menu.
