And london. This is bbc world news. Its newsday. Glad you could join us. Its 9am in singapore, 1am in london and 8pm in florida, where a group of teenagers who survived a School Shooting in the us state have announced a National March on washington to demand action on gun control. They say theyre determined that the mass shooting, in which 1a pupils and three members of staff were killed, will be a turning point in the National Debate on guns. The bbcs david willis has more from washington. After this Florida Shooting it seemed that the National Debate might follow the sort of conventional pattern it has followed in the past. You know, outrage, followed by calls for action, followed by precisely nothing. But now we have these students calling for some sort of action. These are people who, of course, dont remember the columbine massacre back in in 1999. They werent born at that particular time. And unlike columbine, which had outrage but not activism following it, these people are calling for a change and they have come up with various ways of bringing that about, including this scheme to have a march on the capital, washington, dc, next month. That is going to be called the march for our lives. Separately, they are planning a School Walkout on the 20th of april, that marks the 19th anniversary of the columbine massacre and theres a big rally planned for wednesday in the florida capital tallahassee, all basically to advance the calls for tighter gun control laws here in america. David willis there in washington. Lets take a look at some of the days other news. Rescue teams in western iran searching for a passenger plane which disappeared with more than 60 people on board have called off for their search for the night because of heavy snow. Families have been gathering at a mosque close to the airport to get information about their loved ones. Its feared there are no survivors. The plane went down in the Zagros Mountains during a flight from the capital tehran to the southwestern city of yasuj. Amir paivar from the Bbcs Persian Service has the latest. The weather conditions are very severe, the teams that tried earlier on to go to the crash site were unable to do so and they were sent back halfway through because the blizzard is so severe that they couldnt reach anywhere near the crash site. There is no exact knowledge of the number of people who were on board, which is between 55 and 66. That has added to the misery of these relatives. Also making news today. Streets around one of the most sacred sites for tibetan buddhism have been reopened to pilgrims after a blaze broke out on saturday evening, according to Chinese State media. The official Xinhua News Agency said the fire in part of the 1,300 year old Jokhang Temple was soon put out. However, tibetans living abroad said that photos and posts about the blaze were quickly being censored. Well have more on that story in a few moments. A Memorial Service for zimbabwes opposition leader, morgan tsvangirai, has been held in the capital harare, four days after he died from cancer in south africa. Politicians from across the political divide paid tribute to mrtsvangirai. The Bbcs Shingai Nyoka has been watching events in harare. Hundreds of opposition supporters, leaders from across the political divide, as well as diplomats and representatives from some african countries have gathered here to bid farewell to morgan tsvangirai.

Some poignant pictures from syria, where children are returning to schools that have been partly destroyed by the war thats raged for seven years. More than 50 of schools have been affected and students often have to make do without windows, doors or heating. Many of the teachers work without any salary. But as you can see, the children try to enjoy themselves when they can. Russian officials have confirmed that one of their athletes at the Winter Olympics in south korea is suspected of failing a doping test. They havent named the athlete, but some Russian Media outlets suggest it was Alexander Krushelnitsky, who won a bronze medal in curling. He is one of the individual athletes who was allowed to compete, despite a ban on the official russian team because of an alleged state sponsored doping programme. Our correspondent in seoul Stephen Mcdonell has been following the story. There will be a lot of attention on this case today, we have had these reports that Alexander Krushelnitsky has failed a doping test. Now, he won a medal in the teams curling, if he fails a second test, i suppose they will be taking that medal off him. It does draw a lot of attention again to the russian athletes. People will remember theyre not competing here at the Winter Olympics as russia per se, but as these kind of individual athletes under the olympic flag following the doping scandal at the sochi olympics. Broad allegations of doping amongst the russian team at the sochi olympics and they were banned as a team. Many athletes still prohibited from coming, but some have been allowed to attend as individuals, including this athlete in the curling, and yeah, now it seems he has at least failed a first test. The way it happens is that you fail a first test and there has to be a second test that comes along. Stephen mcdonell in seoul. Lets return to the news of the fire that broke out in the most important shrine in tibetan buddhism, thejokhang monastery in lhasa. Chinese state media said the blaze, which started on saturday evening, was soon put out. But the extent of damage to the sprawling compound is unclear. Tibetans abroad noted that photos and posts about the blaze were quickly being censored. It is really the heart of tibetan culture and the tibetan land. Built in the 7th century, the first buddhist temple in tibet. Perhaps one of the oldest timber structures, temples in the world. It has been the centre of pilgrimage of devotion for people all around the world, mongolians and others, for many centuries. It was originally the site of the previous tibetan government before the chinese moved in in the 50s and became a site of major unrest in the 80s and again ten years ago. It is a very sensitive area and terribly important for tibetan people. As you say, religious and politically sensitive. We know that chinas rule of tibet has been controversial, human rights activists accusing china of human rights violations. Whats even more controvertial about this story is that they seem to be censoring some of the reports coming out about this fire, why do you think theyre doing that . Its extraordinary because the chinese dont face a military problem in tibet, pouring money in and trying to win people over through economic improvement. They face this perpetual problem with culture that they dont seem to be very good at handling religion and culture and they have a huge problem with legitimacy. You would think that this would be an issue where they would rush to show people and reassure them that the temple has not been badly damaged, but there is almost no news coming out at all in the last 2a hours. Pictures only of the Party Secretary visiting the temple and telling the tibetans how fortunate they are to have party rule and one or two tiny pictures of the main statue that everybody is worried about in the shrine without any comment and no reference to the fact that there has been a fire. So this is really provoking rumours and uncertainty i think, among the people. Australias Prime Minister, malcolm turnbull, says he has no regrets about a new sex ban stopping cabinet ministers from having sexual relations with their staff. Mr turnbull announced the ban on thursday after it was revealed his deputy Prime Minister, barnabyjoyce, had an extramarital affair with his media adviser, who is now pregnant with his child. Our sydney correspondent, hywel griffith, told me how that new ban is being perceived. Well, its still a running story here in australia. It was announced last thursday as part of Malcolm Turnbulls condemnation of his colleague, Barnaby Joyce, and turnbulls condemnation of his colleague, barnabyjoyce, and the extramarital affair hed had, which is now going to result in him becoming a father again in april. Now, the two men met at the weekend hoping to put their differences aside. Were told they had a good, long discussions. There are two strong characters but their relationship is on track. That however hasnt deterred the story still having some fire left in it, its on the front pages against b let me quickly show you the australian newspaper for example, one of the big sellers here, saying voters berdych, joyce must quit. Its latest poll included a question to voters about whether Barnaby Joyce should quit and according to this one poll it says 65 of voters think he should go. Barnabyjoyce on the front page of the sydney morning herald, you can see him defending himself there against lots of allegations. This paper has been investigating in particular his record of accommodation claims and use public money, mrjoyce insisting hes done nothing wrong there but lots of fire coming in his direction so lots of fire coming in his direction so therefore even more pressure lots of fire coming in his direction so therefore even more pressure on him so therefore even more pressure on him to go this week. When you talked about the two coming together over the weekend and having quite a good chat, but of course ongoing suggestions theres a rift between them. What is being said about that . Yeah, its hard to see how the relationship can really be patched up. I guess if they can survive a few more days and a few more weeks it will all blow over, however mr joyce will be out of you this week, hes elected to take a weeks leave of absence. That might help or it might create a bit of a vacuum for other people in his party who fancy their chances to come forward as leader of the national is to maybe make a very public play against him. So it is all in place. Some people criticising particularly in the more right wing papers Malcolm Turnbulls handling of this, not for the announcement of a sex ban and his critique of barnabyjoyce, but hes not been Strong Enough to push against him. He doesnt have it within his gift to sack Barnaby Joyce, theyre from different parties, but people say this makes him look weak, that hes got a deputy that he clearly doesnt get on properly with, or at least cant condone his behaviour, and therefore the relationship is troubled and alternately doomed. Hywel griffith in sydney. Youre watching newsday on the bbc. Still to come on the programme living the pipe dream in hong kong. These Housing Units are made from, yes, water pipes. Well talk to the architect next. Nine years and 15,000 deaths after going into afghanistan, the last soviet troops were finally coming home. The withdrawal completed in good order, but the army defeated in the task it had been sent to perform. Malcolm was murdered. That has a terrible effect on the morality of the people. Im terrified of the repercussions in the streets. One wonders who is next. As the airlift got under way, there was no letup in the eruption itself. Lava streams from a vent low in the crater flowed down to the sea on the east of the island away from the town for the time being, but it could start flowing again at any time. The russians heralded their new Generation Space station with a spectacular night launch. They called it mir, the russian for peace. This is newsday on the bbc. Welcome back. Im rico hizon in singapore. Im Sharanjit Leyl in london. Our top stories teenage survivors of the florida School Shooting say theyll march on washington to demand action on gun control. After fire ripped through lhasas Jokhang Temple, the extent of the damage to the most important shrine in tibetan buddhism is still unclear. Lets take a look at some front pages from around the world. We start with the South China Morning Post and a report on chinas foundering economic ties with the european union. The paper says the eus investment in china fell by 9. 1 last year, because of frictions over Market Access and other issues. The New York Times is leading with Donald Trumps sons visit to india this week. Donald trumpjuniors main task will be to promote luxury towers, not diplomacy but, the paper says, indians might be forgiven for not making much of the distinction. And finally the front page of the philippine daily inquirer, and this beautiful picture of the start of International Pyro musical competition in pasay city in the philippines. Ten countries are joining the contest to showcase their best fireworks displays. Now, what are people talking about online . The malaysian government is facing ridicule after it took out a full page advert to celebrate the Lunar New Year featuring a barking rooster. The trade ministrys advert wished people a prosperous year of the dog but showed a rooster, barking in chinese. The ministry has apologised for what it called a technical error. The risk of a military clash in the disputed waters of the South China Sea is one that all nations in Southeast Asia are keen to avoid. China and asean have already signed a declaration of conduct at sea and theyre now planning one to cover disputes. The bbcs lyse doucet asked singapores defence minister, whos been attending an International Conference on security in munich, whether he was worried the situation in the South China Sea is generally calm but you asked the question because we just concluded a round table on the South China Sea. It was conducted under Chatham House rules but i think there was consensus. It was notjust a simple issue of who owns what. There are a number of claimant states within the area and if truth be told, all of them have built on disputed features. It is just that china built the most. That will continue to be an irritant. An issue. It will continue to be an issue but despite that i would say that compared to previous years, the fact that we are talking about the area and focusing on confidence Building Measures between asean and china including an agreement that we made an understanding two weeks ago and i think that has brought down the temperature. China has indicated it would like to take on a wider role globally that also includes its neighbours. Do the neighbours sense this in practical terms . In a big way. Not only do you sense it, it is a disruptive change. Compared to ten years ago, the leading trade partner for most of asean countries in australasia was not china. And yet china is the trading partnerfor all of us countries including australia and new zealand. And without the growth of china in the last decade, where you had a recession as will as the Global Financial crisis affecting the us, the americas plus europe, asia would have grown much slowly. In fact we depended on the chinese engine. On the point of view of chinas economic heft you have, if you like, a tide that lifted boats. Beyond that, the one belt one Road Initiative is potentially a very powerful instrument to build up infrastructure in asia, or an asia pacific. And that is substantive. Hong kongs held the title of the worlds priciest city for home buyers for the last seven years, but one local architect thinks he might have come up with a solution. James laws micro Housing Units are made from a rather unusual material concrete water pipes. The stackable pipes are laid on their sides, and each have a kitchen, bathroom and sleeping area all squeezed into an 11 metre square cylinder. James told me what pushed him to come up with the idea. We are struggling with this everyday. The young people here are really struggling to find their first steps in life and to afford a place to live. As an architect i was responding to the pressure that i see every day to find a new kind of design that could inspire them. Do you think this will be popular with people looking for Affordable Housing . I think it is an alternative and i did this project really as a way to generate some positivity and some optimism. I think there is an opportunity to really drive a bit more space, affordable space out about down out of a dense city like hong kong by using this sort of architecture. I have been given a lot of interesting comments and approaches from people who are interested in trying to live in one. So people are not living in them just yet and as you say it is just the design of this page. A bit of a pipe dream, one might say. You think your design is helping address issues of hong kongs scarcity of land . People say hong kong is short on land that it actually isnt. It is just the way that the land is planned in hong kong means that at the heart of our city we are extremely dense and quite expensive. In our city there is still a lot of interesting land left. Land left under the flyover is,
