Family members are scouring the coastline off western Myanmar, a day after a boat carrying at least 70 Muslim Rohingya capsized, but there are no new signs of survivors, a community leader says.
Only eight people have been plucked from the waters alive.
The overloaded boat was in the Bay of Bengal and headed for Bangladesh when it sank early on Sunday, just four hours after leaving shore, said Aung Win, a Rohingya Muslim community leader.
He was speaking on Monday from Sittwe, the Rakhine state capital.
"There were many, many women and children on board," Aung Win said, as he prepared to go to the beach to check on efforts by loved ones to search for bodies.

Dan McNorton, a spokesman for the UN High Commission for Refugees, warned that this year's exodus of desperate people from Rakhine could be one of the biggest ever.
Around 1500 people are believed to have fled, just in the last week, he said.
The agency had received several reports of drownings and was seeking details from authorities.
