About 250 Rohingya and Bangladeshis, including children, are missing after their boat capsized last week in the Andaman Sea, according to the United Nations' refugee and migration agencies, BBC reported. 

The trawler, which had departed from Bangladesh and was bound for Malaysia, "reportedly sank due to heavy winds, rough seas and overcrowding", the agencies said.

The Bangladesh Coast Guard told AFP news agency one of its ships rescued nine people from the vessel on 9 April. It is unclear when exactly the boat capsized.
