The UN refugee agency has said it remains in contact with the Rohingya communities both on Bhasan Char and in Cox's Bazar in an attempt to support the authorities in further rescue efforts following Saturday's boat capsize in the Bay of Bengal.
On the morning of 14 August, UNHCR was alerted that a boat carrying dozens of Rohingyas had capsized close to Bhasan Char island overnight.
"We are devastated that reportedly many passengers, including women and children, have tragically drowned. The confirmed number is not yet known," said the UN agency.
UNHCR said they are grateful to local Bangladeshi fishermen who were first on the scene and alerted Bangladeshi authorities.
The search and rescue operation is being led by the authorities, notably the Bangladesh Navy and the Coast Guard.
"We are seeking further information from the Government of Bangladesh at this time," said the UNHCR.
