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.

Axar.az informs, citing BBC, 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.

Hundreds of thousands of Rohingya, one of Myanmar's many ethnic minorities, have been fleeing across the border into Bangladesh since a deadly crackdown in 2017.

The Rohingya, who are primarily Muslim, are denied citizenship by the government of Myanmar, a Buddhist-majority country.
