Malaysia has stepped up patrols in the waters off Langkawi in the northern straits of Melaka and the Andaman sea following reports that a boat holding dozens of Rohingya refugees is heading towards its shores. The Rohingya boat trying to reach Malaysia briefly stopped on a Thai island, an official said Sunday, as fears grow about overcrowded camps for the stateless minority fleeing violence in Myanmar. Bangladesh has begun relocating 100,000 Rohingya refugees in Cox’s Bazar region to safer ground before the monsoon season for fear of deadly landslides and floods in the congested camps.
