>> In Bangladesh, a welcome is wearing thin. Since last year, a massive wave of Muslim Rohingya refugees from neighboring Myanmar has swept across the border. Their makeshift camps sprawl across what used to be a government forest reserve. Their sheer number is straining resources and has officials and aid workers worried about trouble ahead.
Reuters' Andrew Marshall has visited the refugee camp.>> There are now about a million Rohingya in Bangladesh, and this worries the officials there for a number of reasons. They're worried about the increase in militants activity, they're worried about increase in drug trafficking, and I think most of all they are worried that the Rohingya won't go back.
So there has been a repatriation agreement which was agreed on last year, but repatriation which was supposed to begin in January has stalled now and there's no real sign that it's going to start up again anytime soon.>> So far locals have tolerated the refugees, many feel a sense of duty to help their fellow Muslims and see the Rohingya as victims of religious intolerance.
But at the same time they also blame them for recent troubles.>> They are seeing the prizes rise in the local markets, the prize of potatoes is tripled for example. But they're also worried that Rohingya who would work for much less are coming up to the camps illegally and stealing their jobs.
We spoke to one woman who remembered when the first Rohingya refugees had arrived on her farmland last year. They were crying and it was raining and she felt this great surge of sympathy towards them, and she let them stay. And she said to us, we thought they'd only stay for a month, but it's six months now and they're still on her land and more Rohingya are coming.
>> The UN says, so far there have been no major clashes between Rohingya and Bangladeshis, but it becomes more likely the longer the refugee crisis lasts.>>
