GUWAHATI - Rescuers were searching on Tuesday for about 20 people feared missing after a boat capsized and sank in a rain-swollen river in remote northeast India, a government official said. The motorised ferry was taking about 100 villagers to a popular boat race in Assam state when it hit a bridge pylon and overturned on the Kolohi river late on Monday, a top district administrator told AFP. "The village headman who jumped out first from the boat told us that some 80-90 of his fellow passengers swam to safety," said Vinod Seshan.
