At least 50 people are believed to have drowned in Myanmar when a wooden ferry packed with 178 people collided with a tugboat on a river in the southern Irrawaddy delta region, officials said on Tuesday. Thirty-one bodies were found after the single-deck ferry collided with a tugboat pulling a barge late on Sunday in the Ngawun river, and 21 people were missing, officials were quoted as saying by Reuters. "There is very little chance of finding those missing alive. Most of them are women and children," said an official in Pathein, capital of Irrawaddy, about 120 miles (193 km) west of the main commercial hub of Yangon in the former Burma.
