Sitting in his hillside grocery shop in a Bangladesh refugee camp, Rohingya Muslim Momtaz-ul-Hoque takes a break to listen to an audio recording on his mobile phone, while children and passers-by gather round to hear the latest news from Myanmar.

"I listen because I get some information on my motherland," said Hoque, 30, as he plays a message on WhatsApp explaining the Myanmar government's proposals for repatriating refugees.

Hoque has been in Bangladesh since an earlier bout of violence in Myanmar's Rakhine state in 1992, but the number of refugees in the camps has swelled dramatically to more than 800,000 in recent weeks, after a massive Myanmar military operation sent around 600,000 people fleeing across the border.
