DHAKA (AFP) – Thousands of Rohingya have crossed into Bangladesh since Myanmar announced a military build-up in Rakhine state earlier this month, community leaders said yesterday. Rohingya leaders in Bangladesh said at least 3,500 had arrived since August 12, piling pressure onto already overcrowded refugee camps in the Cox’s Bazaar area. That is despite stepped-up patrols by Bangladeshi border and coast guards, who said this week they had pushed back a boat carrying 31 Rohingya, including children. “In the Balukhali camp alone, some 3,000 Rohingya arrived from their villages in Rakhine,” said Abdul Khaleq. Kamal Hossain, a Rohingya elder in another, camp, said nearly 700 families had arrived in Bangladesh in the past 11 days.
