singapore, and 1am in berlin, where a man—hunt is under way for the prime suspect in the berlin truck attack. he has been named as 24—year—old anis amri, a tunisian who has been in germany since 2015. the suspect had been monitored either security services, at it has been reported that they could not deport him because his key documents we re deport him because his key documents were missing. a reward has been issued for information leading to his capture. the german public have been warned he is likely to be armed and violet. 0ur correspondent has this report. —— violent. you're looking at europe's most wanted man, anis amri, the main, the only, suspect in the investigation into an attack which shattered germany. prosecutors warn he may be armed, dangerous, and they are offering a 100,000 euro reward. translation: there's a new suspect. we are searching for him. we'll keep investigating every lead. we issued a issued a warrant for

this suspect‘s arrest at midnight. it covers all of germany and most of europe. we are learning more about the 24—year—old tunisian. he arrived in germany last year and was refused asylum, but granted temporary leave to stay. the security services admit he was known to them are considered a threat because of his links to one of germany's most notorious to islamist networks. and he will be hard to find. he used six different names, and three nationalities. translation: this person attracted the attention of several security services in germany, through his contact with a radical islamist. the hijacked lorry is yielding grim evidence, documents leading to the suspect, and dna. it is thought amri fought with the man should have been behind the wheel, before shooting him dead. but it was 2a hours before police identified him as a suspect. first they arrested and released

an innocent man, giving amri a vital head start. today, flowers for the dead, prayers for the injured. the german foreign minister was joined at the scene of the attack by his italian counterpart. among those missing, and feared dead, fabricio dilorenzo, who comes from l'aquila. dalia elyakim, who is from israel, also hasn't been seen since the attack. her husband, rami, is seriously ill in hospital. a time perhaps for faith. tonight, a spontaneous gathering at a berlin synagogue. the ceremony was extremely important, because this attack was not an attack on berlin, or on germany. it was not an attack on jews or on christians. this was an attack on all of us. across the city, a vigil of a different kind. the attack, the arrest warrant, have reignited a national debate.

the anti—immigrant party alternative fur deutschland blame angela merkel and her refugee policy for this attack. so does geert wilders. the far—right dutch politician posted this picture today, the german chancellor's hands covered in blood. do you blame angela merkel? angela merkel, she says, is a humanitarian woman. she did the right thing a year ago. no—one could know this would happen. we live in a free world. and if we want to stay free, things like this will happen. this country feels nervous. extra security at christmas markets. after all, amri is still at large. but this investigation does now have a face and a focus. that is for some here, perhaps, a little light in the darkness. also making news today: indonesia

say they have killed three islamist suspects during a gun battle on the outskirts of the capital, jakarta. the neighbourhood had to be evacuated while experts tried to defuse several bombs. police are linking the militants to another group that was captured earlier this month. japan is scrapping an experimental nuclear reactor that has already cost the country $9 billion to run. the troubled monju reactor in fukui city was designed to burn its own spent fuel, removing the need to deal with nuclear waste. but it has suffered numerous problems, and operated for only 250 days in 22 years. the final phase of the evacuation of rebel—held eastern districts of aleppo has restarted, after being stalled for a day. the international committee of the red cross says it has now brought out all hospital patients from the syrian city, as well as those needing medical care.

the condition that they face there we re the condition that they face there were horrific. months of siege, bombardment. so they are in a very bad way in deed. they will access this care and then they will be able to choose where they want to go next and most will choose to go to the last remaining stronghold of the opposition in syria, which is edited, a large city in the north of syria. —— police in australia are investigating the explosion of a van filled with gas bottles, which crashed into the australian christian lobby headquarters in canberra. the spokesman of the lobby group has said it was an attack on free speech. the group is opposed to gay marriage. but police have not yet said if they are treating the incident as suspicious. the driver was the only person injured in the incident, and is being treated in hospital. 0rganisers in tokyo have unveiled a budget of $16.8 billion for the hosting of the 2020 olympic games. it is down slightly from last

month's proposal, after they came under pressure from the international olympic committee to cut costs. but the figure is still more than double the original estimate. american singerjames taylor has cancelled an upcoming concert in the philippines, to make a political stand against the extra judicial killings that have taken place since president rodrigo duterte came to power. mr taylor said the summary executions of suspected offenders were unacceptable. construction workers in peru got a surprise when they came across a crocodile on a worksite. the two—metre—long reptile was discovered in the city of puerto maldonado in the south—east of the country. it had apparently wandered over via a canal connecting the site to a local ranch. the crocodile was handed over to local forestry workers, who dropped it off at a zoo. let's go back to our main story, the manhunt for anis amri,

the tunisian who is suspected of being behind the attack on the christmas market in berlin on monday. joseph cirincione is the president of the global security foundation ploughsha res fund. i asked him whether the german authorities could have done more to prevent this attack. terrorism of this kind is extremely difficult to prevent. was this individual... did he commit the act because we didn't deport him soon enough, or was he disturbed individual who committed the act because he was about to be deported? we don't know yet. but we do best. ever since the terrorist attacks of 9/11, national security experts including myself have been focused on the next big, catastrophic terrorist attack, another well—planned, highly co—ordinated attack, perhaps involving nuclear

weapons or dirty bombs. well, it turns out that is not the kind of terrorist attack we actually have to worry about. it is now this spread of low—tech terrorist attacks, dispersed, autonomous, inspired attacks. it turns out that knives and semiautomatic weapons and home—made bombs, and our trucks, are perfectly adequate for causing the kind of terror and societal disruption that the terrorist seek. something like this, an individual, maybe acting on his own, may be part ofa maybe acting on his own, may be part of a larger plot, is extremely difficult to stop. and i don't see any way that the authorities could have prevented this kind of attack. why the change in the strategy than by terrorist organisations, with this kind of tactic you describe? because it works, because it's cheap. this individual, was he in with isis, he doesn't have to be. —— was he in communication with isis? he doesn't have to be. perhaps

inspired by isis or perhaps just made, literally insane, who are acting out of way they are reading about about in the papers. it is very ha rd to about about in the papers. it is very hard to stop someone like this, to stop it from happening. we open societies, we are extremely vulnerable to this kind of attack. i will tell you what this will do, however, it is not going to disrupt germany, it is not going to stop germany, it is not going to stop german foreign policy, but it may fracture german political, domestic unity. you see what this is doing. it is fuelling the rise of far right parties. they are seizing on incidents like this. even though we all know more people die from lightning strikes than from terrorism. more people die in bath tub accidents than from terrorism. these kinds of attacks, particularly involving what are traditionally considered non— europeans, it is fuelling the far right in europe and here in the united states as well. i'm not sure if you had what donald trump had to say in response to the berlin attacks today, but he says this proves he was right all along

to propose curbing muslim immigration to the united states. what is your assessment than of where that leaves the conversation regarding america's response to this? so on and in intellectual level it is an absurd comment. of course it is not right. of course it is crazy to ban religion, to ban a belief, and stop all people from the muslim faith of entering the country. no rational person thinks thatis country. no rational person thinks that is right. but as a political slogan it fuels his base, it feels his support. but what worries me more is not the ad hoc comment, it is what some of his advisers are doing. two weeks ago, general flynn, the man that donald trump has tagged to be the next national security adviser of the united states, met with the head of the austrian freedom party, a far right neo—nazi party. this is a party literally founded by a nazi in 19 86, party. this is a party literally founded bya nazi in 19 86, a party. this is a party literally founded by a nazi in 19 86, a former ss officer. and bake water unaided, they planned, the same individual just concluded a cooperation

agreement —— 1956. with the leader ofa agreement —— 1956. with the leader of a foreign party, putin, in russia. this is an extremely troubling development. china has been enduring some of the worst air pollution of 2016. now there could be some relief in sight from the smog. beijing is to lift its red alert emergency measures, as a front of cold air approaches. near—record levels of toxic air have prompted the authorities to ground planes, shut factories and close schools. but as david campanale now reports, the problems of pollution won't be going away. it is not just it is notjust the capital, beijing, that has been under a suffocating blanket of smog. much of the country has endured six days of an oppressive haze, sparking public anger about the slow response to the threat to health. since friday, emergency measures have attempted to soften the impact of a choking my

asthma across a large swathe of north—eastern china. 460 million people, in more than 20 cities, have been gasping for breath. at the crisis will not be eased quickly. what we see today is the consequences of the sins of probably a whole generation, development, fast development, which clearly had did not have the environment at its centre. there is signs, though, of temporary relief. the national weather authority says the arrival ofa weather authority says the arrival of a colder weather front will disperse the smog and ease conditions. emergency measures such as car restrictions, based on even, odd, licence plate numbers, will be ended, and schools will resume classes. but levels of particulates tiny enough to be absorbed into the bloodstream remain skyhigh. 20 times the world health organization's daily recommended maximum. these are

a major contributor to respiratory and heart disease. and with forecasters saying that next week settled weather will see the return of smog conditions, policymakers will need to find longer term solutions. you are watching newsday on the bbc. still to come on the programme: could the world's biggest fish market be on the move? we report onjapan's tsukiji market. also on the programme. india is cracking down on airlines releasing human waste from toilets in the air. we have a special report. we saw this enormous tidal wave approaching the beach, and people started to run, and suddenly it was complete chaos. united states troops have been trying to overthrow the dictatorship of general manuel noreiga. the pentagon said the operation had been 90% successful, but it's failed in its principal objective, to capture general noreiga and take him to the united states to face drugs charges.

the hammer and sickle was hastily taken away. the russian flag was hoisted over what is now no longer the soviet union, but the commonwealth of independent states. day broke slowly over lockerbie, over the cockpit of the pan—am's maid of the seas, nose—down in the soft earth. you could see what happens when a plane eight storeys high, a football pitch wide, falls from 30,000 feet. christmas has returned to albania after a communist ban lasting more than 20 years. thousands went to midnight mass in the town where there were anti—communist riots ten days ago. this is newsday on the bbc. our top stories: a manhunt for the berlin market attacker. anis amri has been linked to an islamist network. relief in sight for chinese cities — forecasters say the choking smog is set to clear.

ikea, the home furnishings retailer, has warned that teenagers who have illegal sleepovers in their stores are guilty of trespassing. ikea has recorded about 10 such incidents in countries including japan and australia. let's take a look at some front pages from around the world. we start with the japan times, which says the former secretary—general of the united nations, ban ki—moon, is considering standing for the presidency of south korea. the paper says he's willing to devote himself to helping south korea in the wake of the scandal surrounding president park geun—hye. the china daily business section leads on chinese tech giant lenovo, which is scaling back its operation in brazil. it says beijing—based lenovo has cut its workforce in brazil from 5,000 staff to 800, because of declining consumer demand, according to local media. and the philippine star says

president duterte has told his armed forces to respect human rights and the rule of law in all their operations. but the paper says he also stressed there is no stopping his bloody war against illegal drugs, which has drawn international criticism. and this story is trending online. a favourite singer of mine has helped some passengers on a flight. absolutely, we know that you love soft rock. that is why this story is particularly appealing. do you remember the 1990s pop star richard marx? well, he's famous again for helping subdue an airline passenger. the scuffle was aboard a flight between vietnam and south korea. luckily for all, the singer was "right here waiting" when the trouble broke out. do you get it, rico?

# right here waiting for you. mac moving on. this might not be a story for you, if you live the lower flight for you, if you live the lower flight path. —— bulow a flight path. india is cracking down on airlines release human waste from toilets in the air. it follows complaints that an aircraft had been dumping waste over houses in delhi. they'll face heavy fines of 50,000 rupees — that's more than $700. 0ur correspondentjustin rowlatt braved a trip to the airport. so, the claim is that planes are regularly discharging their toilets over the indian capital. a retired indian army officer claims his alchemy, very near where i am standing outcome is regularly splattered with human excrement. —— balcony. he cannot prove that this is from planes, but his complaint was taken up either national green

tribunal, an environmental court, and it has ordered that india's aviation regulator makes sure that airlines do not dump human waste in this way. the plan is that there will be spot checks on plane to i lets. will be spot checks on plane toilets. the special tanks used to store human waste are suspiciously empty, the airline could face a fine of up to 50,000 rupees. that is $800, or £600. how plausible are this guy's claims? well, a senior indian pilot told the bbc today that planes do sometimes have to discharge waste from their toilets. he said this is a very rare emergency event, a bit like when they discharge fuel to reduce the weight of a plane. there is, however, another way in which human waste can be as discharge from a plane. these are known as blue ice falls. there are overflowed pipes from the tanks, and waste can build up from the tanks, and waste can build up around those pipes. because planes fly at a high altitude, it is

very cold. that can build up into a block of ice, which can fall from a plane and occasionally cause real damage. earlier this year i reported ona damage. earlier this year i reported on a woman here in india who claimed she had almost been killed in a blue ice fall. britain's civil aviation authority says that 25 blue ice falls are reported in britain every year from falls are reported in britain every yearfrom 2.5 million falls are reported in britain every year from 2.5 million flights. whether the measures introduced today will do anything to reduce the risk of being dumped on in this way remains an open question. for sure, forsure, i for sure, i would for sure, iwould not for sure, i would not want to live below this flight path. the next story is quite interesting. i have been to displace many times to eat my sashimi and sushi. i have been there too. biju go very early, about 4:30am ? yes, i love it when people are trading and buying and selling fish

and seafood. it is wonderful. eating everything, the sashimi and the sushi is very fresh. yes, it is wonderfully fresh. japan is home to the world's biggest fish market, called tsukiji. it's legendary for tuna auctions, the source of all that great sushi. so much so that a plan to move the market has proved controversial. now a film has reignited a debate over its historic value. the movie's director, naotaro endo, told the the bbc what makes the marketjust so unique. translation: when i first visited tsukiji, i was surprised. i was struck the power of the people who make it it is. i was captivated by

the energy and decided i wanted to make it into a movie. trust is the key here. getting them used to you. it is based on family businesses, and how people connect with each other. through the movie, i hope it can

provide an opportunity to discuss how to nurture and pass on our asian food culture to the next generation. —— ancient food culture. you know, iwouldn't you know, i wouldn't mind having a sushi breakfast today. now, many people would be grateful just to be alive when they pass 100 years — but not professor david goodall. the scientist is determined to remain working, despite his advanced age. he was told he was a health and safety risk by his employer, edith cowan university in western australia. but now professor goodall has won his age discrimination battle. hywell griffith reports. after seven decades as an ecologist, david goodall says his natural environment is here, on campus,

surrounded by academic life. in august, the centenarian was told it was no longer safe for him to come into work at cowling university, and he was asked to stay at home. —— edith cowan university. but after his case one international support, management has relented and found him this new office. i have only been here one day, so it is a bit difficult for me to express any particular concerns, but i think that they will try to make me at home. the journey from home will be much quicker. reaching his old office involved a 90 minute commute ona office involved a 90 minute commute on a train and two buses. the university says they have always had his interests at heart. first of all, it is closer to his residence, so it is easierfor him to commute. secondly, there is an office that is manned nearby most of the time, so we can keep an eye on him and make

sure he is ok. having forced to give up sure he is ok. having forced to give up his other love of acting, professor goodall is determined to keep his mind active. at 102, he is not out yet. you know, what i am so proud of about professor goodall is that he is spending his 102nd christmas. i know that you will not be with us tomorrow for newsday, but have a happy christmas and a more prosperous 2017. hgppy prosperous 2017. happy christmas to you too, ricoh, and to everybody in singapore. we do not have a christmas hat here in london. you look wonderful, though. i know you have the naked boy this year so i think santa will pay you a special trip indeed. —— you have been a good boy this year. stay with us, we will be back soon. hello there. the run—up to christmas
