At least 31 people have been killed and more than 100 injured as a wooden suspension bridge collapsed at Bijanbari, 40 kilometre from Darjeeling in West Bengal, Indian media reported on Sunday. While 10 people died on the spot, the rest succumbed to their injuries in hospitals. The death toll may rise as some of those injured are critical, reports said. Over a 100 people had gathered on the bridge to listen to a religious leader, an official said adding that the pressure of the crowd led to the collapse of the bridge. The suspension bridge was built in 1972. It was meant for pedestrians but over time was used by motorcycles which weakened it, he said. Indian Army's Mountain Brigade at Darjeeling has sent troops to the site for assistance. The West Bengal government has announced a compensation of Rs. 200,000 to the families of those killed in the mishap. State Disaster Management Minister Javed Khan said all seriously injured persons were being shifted to the North Bengal Medial College Hospital.
