Some 20 people died and about a dozen were missing on Friday after a wooden boat carrying about 60 wedding guests hit a cargo ship and sank in southwestern Myanmar, local officials said.
This is the third big marine accident in the country in many years.
The boat was unlit and hit a cargo ship on the river in the city of Pathein at about 7:20 p.m. (1250 GMT), they said.
Twenty bodies have been found and 27 people have been rescued, Kyaw Myint, a local government official, said from a hospital in Pathein.
Rescuers were still looking for survivors, a witnesses said.
“The authorities at the port are looking into the cause of the crash,” Kyaw Myint said.
The regional government will help arrange funerals, he said.
“It’s a huge tragedy because there were a lot of women and children on the boat,” Khin Zaw Lin, a parliamentarian for the ruling National League for Democracy (NLD) party, said.
Marine accidents are common in Myanmar, where many people rely for transport on crowded and dilapidated boats. Seventy-three people died in a ferry accident in October last year, and 64 in an accident in March 2015.
