At least ten people have been killed and 150 injured after a portion of an overpass under construction collapsed in a congested area in the eastern Indian city of Kolkata, officials said.
Efforts are underway to rescue those trapped under the debris. Many cars, trucks and rickshaws were seen under the large chunks of concrete and metal debris.
The injured were admitted to two hospitals in Kolkata, the capital of West Bengal state, hospital officials said.
Building collapses are common in India, where builders use poor enforcement of regulations and use substandard materials.
