At least 12 people died and scores were missing after a boat packed with Rohingya.
Bangladesh authorities said, the boat sank near Shah Porir Dwip, on the southern tip of Bangladesh.
Coast guard and border guard officials said the boat was overloaded with about 100 people when it sank in the mouth of the Naf river that separates Myanmar from Bangladesh.
Bangladeshi police officer Mohammed Mainuddin told Reuters that 12 bodies – 10 children, one woman and a man – had been recovered.
Nearly 520,000 Rohingya Muslims have fled Rakhine state for Bangladesh since late August after the military in Myanmar launched a crackdown following attacks by Rohingya militants.
The United Nations has said the army campaign could amount to ethnic cleansing while Myanmar military leaders have blamed the unrest on the Rohingya.
