Officials say dozens of people are missing after a crowded ferry sank on Bangladesh's Meghna River on February 8 after colliding with a sand barge.
Local official Muhammad Saiful Hassan Badal said about half the passengers managed to swim ashore and a search has been launched.
It was not immediately clear how many people were on board.
Survivors said the ferry was carrying around 100 people.
According to local officials, the vessel was not overloaded.
The Meghna River is one of three rivers that form the Ganges Delta. Bangladesh has a history of boat disasters as a result of poor safety standards and the frequent overloading of vessels.
Last March, 147 people were killed when a passenger vessel sank in the Meghna River after colliding with a cargo ship.
