Qa'dah 11, 1431, Oct 19, 2010, SPA -- Efforts to find a bus with 19 people swept away by high waters were hampered by raging currents Tuesday in central Vietnam as the country's overall death toll from flooding and heavy rains reached 41, officials said. Eighteen other people on the bus swam to safety or were rescued after clinging to trees and power poles. The bus was yanked off the main highway while traveling from the central highland province of Dak Nong to the northern province of Nam Dinh early Monday morning, Phan Van Dan, a local police chief was quoted as saying by the Associated Press. The bus bypassed a police roadblock diverting traffic from the highway, which was covered by up to 24 inches (60 centimeters) of water. The driver survived and was being questioned by police, Dan said.
