The United Nations has called for an investigation into the killing of burundian refugees in the east of the democratic republic of congo. The un force in congo says the Congolese Security forces shot dead 37 refugees and injured 117 others. It said one soldier was killed in the incident which began when the refugees protested against the expulsion of four burundians from the country. Andrew plant reports. The bodies of burundian refugees apparently killed when Security Forces opened fire. Officials in the democratic republic of congo say the refugees were attempting to break into a secure compound. This camp, just a few miles from the border of burundi, now home to thousands who fled outbreaks of violence in their country which erupted there more than two years ago. Translation the Security Forces in the democratic republic of congo threatened to kill us in case we did not want to return home to burundi. Justice must be done. Many more have been injured in the violence at the camp, basic medical care given at the side of the road. Opponents of burundis president , pierre nkurunziza, say his move to stay in office for a third term in 2015 was illegal. The clashes that followed caused tens of thousands to flee, opposition rallies crushed, with rumours of abductions and torture. In france, regular demonstrations are taking place to try to draw International Attention to burundi, and a situation that many say could escalate into civil war. Translation there are people dying every day in burundi and they close their eyes. So perhaps, were here to move them a little, perhaps to open their eyes they are trying to close. Its very, very hard. The government says the People Killed were members of an armed group who had attacked an office of the National Intelligence agency. The Un Refugee Agency has called for a full investigation, and has sent medical teams to help treat more than 100 who have been injured. Lets go to bangladesh now, where the government is planning to build a giant camp for the 400,000 ethnic rohingyas who have fled from neighbouring myanmar. The government says it will also impose restrictions on the movement of the rohingyas in order to prevent them from settling in other parts of the country. 0ur South East Asia correspondent Jonathan Head has the latest from coxs bazar. When they first started crossing the border three weeks ago, bangladesh said it would send the fleeing rohingyas back. With 400,000 already here from previous outbreaks of violence, the government believed it could not take any more. But the unprecedented surge in numbers of rohingyas has forced bangladesh to reconsider. It now wants to build a vast camp adjoining an existing one in which it hopes to accommodate all 400,000 of the new arrivals. The police say they will also enforce restrictions, barring the rohingyas from moving elsewhere. There are questions, though, over how fast this can happen. The displaced rohingyas are in desperate need of the most basic aid. They are, in many cases, sleeping in the open with no sanitation or water supplies. Until now, the Un Refugee Agency has been restricted to the relatively small numbers around 70,000 living in official camps. Un officials hope that the government will now consider a wider role for various un agencies, so that a full scale relief effort can be organised. Jonathan head, bbc news, coxs bazar.

The move could affect nearly 300,000 passengers who will be offered alternative flights or refunds. Many have complained about the short notice of the cancellations. Our Business Correspondent joe lynam reports. It is europes Busiest Airline but it is grounding hundreds of its own planes. In doing so, it is ruining holidays for thousands of its own customers, some of whom are now stranded overseas. Carrie ann woodgate is in wroclaw, in poland, and was e mailed by ryanair. The next flight out of wroclaw is next thursday. We cant get through to anyone at ryanair, we cant get through to a manager. Live chat doesnt work, the app doesnt work. If you do ring ryanair on customer services, all you get is, were having a very large volume of calls. You betcha others have had to cancel their holidays. They text me the evening before the morning i was supposed to fly out. So, yeah, pretty disappointed. Lost a holiday out of it, and lost some money as well. Ryanair says that air Traffic Control issues and weather, as well as a surge in pilots and cabin crew taking their holidays, is forcing it to ground up to 50 flights a day until the end of october. But that is still only 2 of the airlines entire flight schedule. But passengers set to fly with ryanair in the coming weeks simply dont know whether their flight will actually take off. It could be cancelled right up to the moment they arrive in the airport. The spin that ryanair is putting on this is saying we want to make our timekeeping better, so therefore, were putting more planes on the ground in case something goes wrong. I must say, from the passengers perspective, someone like me, who has got a booking on ryanair in the next few weeks, that looks like total tosh. Basically, it is a massive administrative foul up. All their cabin crew and pilots are taking their holiday before the end of the year. So what could you get back if youre affected . Well, eu rules say you are entitled to a new flight or full compensation if your flight is cancelled. The airline also has to cover your food and accommodation if youre stranded, and it should offer to pay for a flight with a rival airline if it cant get you on another flight to your final destination. All this means that these cancellations could cost ryanairs enigmatic boss, michael 0leary, up to £100 million. It is difficult to put a price, though, on damage to the airlines reputation.

He proudly served his country in Northern Ireland, iraq and afghanistan. However, his life was changed forever when his vehicle drove over an improvised explosive device, or ied, while on a routine patrol in helmand province, in 2013. My only overriding memory of that whole time was the fact that because i could still see i was still alive. And that moment that your wife and yourself locked eyes, that must have been quite a moment for her as much as for you . She knew that when she saw me for the first time in hospital that despite the injuries and the number of limbs i was missing at the time, she knew it was me. I was walking about when i got out of hospital, trying things, different sports, and ive used the Invictus Games as a massive tool to get on the road. Its a process i know well. After i was injured 13 years ago, i was introduced to wheelchair rugby and eventually captained the Gb Paralympic Team at london 2012. Its crazy to think that you watched me play in 2012 as captain. And now youre there, Invictus Games captain, going onto your second as well. I know.
