The 100-foot-long (30-meter-long) bridge gave way as more than 150 mountain villagers gathered on it Saturday night to hear speeches by local officials in Bijanbari, about 20 miles (30 kilometers) from the hill town of Darjeeling. The bridge was built in 1942 and weakened by a September earthquake.

Authorities say some who fell about 100 feet (30 meters) into the swirling Rangeet Khola River were likely swept away in the rapids. Rescuers searched Sunday in areas downriver.

West Bengal state police official Surajit Kar Purakayastha says more than 100 people who were injured in the collapse have been found.
