New Delhi, Nov. 10 -- Two boats carrying over 300 members of Myanmar's Rohingya community sank near the Thai-Malaysian border in the last two days. Authorities fear hundreds of casualties.

Malaysian authorities said on Monday that so far, search teams have recovered seven bodies and 13 survivors. Thai officials reported earlier the same day that their search had found four dead.

One boat carrying around 70 people sank in waters near the Thailand-Malaysia border on Sunday, while the fate of another vessel with about 230 passengers, which sank on Saturday, remains unclear.

Rescuers are combing an area of 170 square nautical miles near Langkawi island after a boat with 300 people left Myanmar's Rakhine state three days earlier.
