>> it's one of the biggest dinosaurs ever discovered so big it barely even fits in this museum. that story coming up hello. ipdn police is searching for the man the main suspect in the jakarta attacks. a man linked to i.s.i.l. is syria is the chief coordinator behind the blasts. at least two civilians and five attackers were killed. police have arrested three men suspected to be linked to the attacks. indonesia has been targeted in the past and security had already been tightened following recent threats from i.s.i.l. it has been raised to an alert one status, the highest. the day after the bombing there is a semblance of normalacy.

a peace rally is planned in the coming hours. more on the reaction this morning a day after those attacks in jakarta and tell us about these arrests that have been made. >> reporter: yes. it's still filtering out. we had an idea that, obviously, the authorities were going to be arresting people as soon as they had some sort of information and intelligence as to who might be behind these attacks. they made some arrests on thursday. it was still very grey as to how many arrests have been made, but apparently three people have been detained for questioning. the police and authorities are still very unclear in telling the media whether they are connected to the bombings or not, but they are continue withing their lines of inquiry. we wait to see whether there will be an announcement later in the day. there was a question as to whether any of the perpetrators or coordinatorss of this attack might have got away.

that is still a very large question that's looming over the security services as they continue their inquiries into the investigation. the real clues are in the five attackers that were killed and really the questions around who they were, where they came from and how they got to jakarta, how got the ammunitions for this attack, who gave them those and where did the finance come from. i think once those questions can be answered by the authorities, they have more definite lines of inquiry that they can pursue. it has been said by the security minister, who has been interviewed by al jazeera, that the wife of one of the attackers has been arrested. we're not sure whether it is wife of an attacker is dead or detained or on the run. what the authorities are alluding to is that that suspect might have been the coordinator

on the ground here in indonesia or there is a mastermind of the name of baroon may who is in iraq of indonesian descent known to the authorities who might have been the master behind this attack what does this mean for the investigation? where does it go from here? >> reporter: the investigation, of course, continues. life is beginning slowly to get back to normal. there is a heightened sense of security around the area here where there are international guests, tourists, areas where people gather in large quantities. we're talking shopping malls, cinemas, which is what happened on thursday. in terms of the proceedings during the day we are expecting to hear a statement being made by a group of senior clerics who

after friday prayers will certainly - apparently will be making a clear condemnation of what happened and also in a few hours time we are expecting a peace rally outside the mall to show solidarity with those people that were injured or killed and, programs, to show the wider public that indonesians are not deterred by this and making sure that such acts of violence do not occur on indonesian soil again thank you for that. u.s. republican presidential hopefuls have been taking part in their sixth debate. donald trump and ted cruz clashed on the stage. a night of heated exchange,

heated debates between the candidates. >> reporter: when you get this close the pressure builds and there were only seven candidates on the stage. then you really have to stand out. one of the ways to do that is to attack the other candidates. this was a very fiery night on the stage. we saw ted cruz attack donald trump, we saw him attack marco rubio, we saw marco rubio come back with fire. we saw jeb bush spring out at anyone in his way. it did get quite nasty at points. it really was heated. hot words and low blows. one of the most heated exchanges came with donald trump suggesting that ted cruz couldn't stand for president of the u.s., couldn't be the nominee because he was born in canada. ted cruz simply wasn't having any of that >> back in september my friend donald said that he had his lawyers look at this from every which way and there was no issue

there. there was nothing to this further issue. [ laughter ] >> since september the constitution hasn't changed. [ laughter ] >> but the poll numbers have. you're an american as is everybody else on this stage and i would suggest we focus on who is best prepared to be commander in chief besides the strong words that were used, how much did this debate highlight policy differences between the candidates? >> reporter: i think this was really important. this is the sixth debate we've seen and, perhaps, we were getting clear ideas for the first time of where the differences exist. they're all united in the fact that they don't like obama and his presidency and that hillary clinton will make a terrible president, but things like immigration there are clear differences.

donald trump says to ban all muslims. jeb bush said all muslims, seriously? he thought it was a bad idea. marco rubio and ted cruz have a go at each other about letting immigrants from south america into the country and how they have voted in the past. then there is how do you deal with the question of trade and with china, how do you change the tax system here, is it the way that ted cruz wants to do it, which is called a value-added tax system or a flat tax like ben carson. this was a very fiery debates. these have been getting millions and millions of viewers. this will give you a clear idea of where the candidate stood on certain issue and that may make it clearer when it comes to voting. what why ask that important? iowa is just 18 days away. this seems to be a very long campaign but in 18 days we will get the first real test of voters. who won the debate?

fk had a goodnight, although he did struggle when marco rubio came back at him. jeb bush had his best debate but it might be too late for him. chris christie did okay. donald trump look rattled but came back strongly. in the poll that was conducted by google at the end of the debate it said donald trump was the winner. we will know in 18 days it sounds like it. thank you. the u.n. secretary general has warned the war in syrian is using starvation as a weapon. ban ki-moon has called it a war crime. an emergency meeting on friday will be held on friday to end the sieges. more from the u.n. headquarters in new york. >> reporter: more aid is finally delivered to the starving people of madaya, a town blockaded by the syrian government. this is the second delivery of food and medicine this week, but before that the town was cut off

for three months. at least 28 people died from starvation. in some of his strongest comments yet after almost five years of war in syria, the u.n. secretary general ban ki-moon told the u.n. general assembly this was a war crime >> >> the town has been the victim of deliberate starvation. let me be clear. the use of food as a weapon of war is a war crime. all sides, including the syrian government, which has the primary responsibility to protect syrians, are committing atrocious acts prohibited under the humanitarian law. >> reporter: he told the besieged areas where 400,000 people are cut off from food and assistance should be on the agenda at syrian peace talks in geneva due to start in ten days.

>> i think in addition to and parallel to political negotiation is how to deliver humanitarian assistance without any impediment should be discussed. this is a very important confidence-building measures >> reporter: the u.n. security council will be meeting to discuss the besieged areas in syria in an open session on friday and despite the fact that bang key moon has described these as war crimes, the council won't be taking any action on th that. a referral to the international court requires a quote on the security council and it is certain that russia and china would use their veto al-shabab fighters have rammed a suicide car bomb in somalia. there are no reports of casualties after fighters battled their way onto the base.

the governor aden was killed. following that the deputy governor of aden introduced a dawn to dust curfew. he said it saved lives but what is needed is an end to the fighting. >> translation: there have been achievements, but this is a braulgts war between government forces and those loyal to the abouted and they are still fighting but god will help us. >> reporter: an alliance of houthi fighters backed by troops of the u.a.e. drove the president outed of aden six months ago. forces loyal to the president have made advances in the city port city but people worry about the lack of security. >> translation: the security shouldn't be the only one

responsible. it is a huge challenge. social groups should be involved. >> reporter: despite the instability in aden the president is trying to build confidence in the government's ability to protect its citizens. on thursday he went to a graduation ceremony at a military base and visited the port as it was brought back under control border controls have been reinstated between sweden and denmark, but a new sea route has opened up for refugees and it could be the most dangerous so far. separately, al jazeera understands danish activists have transported dozens of refugees to sweden. >> reporter: half past 9 in the morning and the migrant reception center in the city is already full of people. these men, women and children are all new arrivals which means

they've all come in the small period since sweden introduced border controls to try and stop them. one way or another they're still finding a way >> there is the possibility to still get to sweden in some other way, some kind of illegal entry and that will still happen. >> reporter: by road and rail the obvious routes linking the areas to sweden, the authorities are checking people's credentials, but some have still found a way through in car boots and trucks. the sailing culture and liberal activism is playing to the refugees' advantage. these people are part of a bigger group which has carried dozens to sweden because they already have families there and it is free of charge. they do not fit any profile of what you regard people smugglers as looking like. >> when you think about smug letters, you think about people earning a lot of money from helpless people. that's what we're doing.

we're helping people, we're giving them food, we're good sailors and we're not charging anything to do. >> reporter: whether there are good sailors to help refugees cross this forbidding sea, far more dangerous attempts are beginning to happen. at least one rigid inflatable boat as one seen between turkey and greece has made this crossing. if you capsized here in a storm, you wouldn't last half an hour. no wonder the swedish coast guard has been put on high alert. >> it has been more dangerous for them and the water is super cold by now. it could be rough weather and most people are not prepared for those kind of waters. >> reporter: this isn't the first time that the sound between denmark and sweden has been used as a people smuggling route. during the second world war when kopenhagen was occupied by the

nazis, jews were taken across. the reason why people smuggling route has grown up here is because the countries have closed their borders for refugees. many people don't see them helping refugees but as criminals who should be arrested. if the border controls go on, then inflatable dinghys may be the choose for refugees who want to see the family across the water. that would be the most desperate journey a politician from the southern german state says his district can't cope with the influx of refugees and has sent some of them to chancellor an gem amerkel's office in protest. a bus kaerning 31 syrian refugees arrived. this man says his town was reaching its capacity.

>> on i was really heartened by the resillen see of the citizens of flint. -- resilience ee. this is obviously not a good situation but resilient. >> reporter: problems were first reported in 20104 when the city changed its water source >> i have very rarely used the city water >> reporter: you don't drink it will? >> not at all. >> reporter: this woman told the people in september the water had left her with a rash. >> i itched and scratched. now she wants to know why it took the city too long to act >> they didn't decided to do anything until they find led. n i have a problem with that issue. >> reporter: are you happy they're doing something now? >> yes. i am. >> reporter: after months of

2014. it took a team 18 months to excavate the more than 200 bones. unlike most huge dinosaur remains are fractured, most of these were intact >> you need a big skeleton to understand these animals as living organisms. this is what we can do now with this highly complete skeleton we can for the first time be able to answer those questions. >> reporter: some of the remains were sent to a laboratory in canada where a cast of the entire dinosaur was made. a team of workers at the american museum of natural history in new york then put the dinosaur back together, an arduous task unlike anything the museum has every undertaken. it is on display for young and old to gaze apt and admire now
