The Bangladeshi government has announced plans to build shelters for up to 400,000 Rohingya Muslims fleeing from neighbouring Myanmar. The army and aid agencies are due to erect 14,000 shelters, each housing six families, near the city of Cox's Bazar. Since late August over 400,000 Rohingya are thought to have fled to Bangladesh, to escape a government offensive.<br/><br/>Meanwhile, a fresh diplomatic row between Bangladesh and Myanmar has broken out over alleged violations of Bangladeshi airspace in the past week. Bangladesh Foreign Ministry summoned the Myanmar envoy and strongly protested the instances of violation of the country's airspace by Myanmar's military drones and helicopters on 10, 12 and 14th of this month. Foreign Ministry sources said Bangladesh expressed concern to the envoy Aung Myint and handed him a protest note saying these provocative acts may lead to unwarranted consequences. <br/><br/>According to sources, Myanmar's helicopters and military drones have violated Bangladesh air space more than 20 times since the military crack down on insurgents on August which has led to a constant influx of Rohingya refugees into Bangladesh. This is the fifth time in 3 weeks that the envoy has been summoned and handed over protest notes.
