KOLKATA: Four people were killed on Sunday in a “crude bomb” blast in a slum in India’s eastern city of Kolkata, police said.

Police said the device was left at a garbage dump in a slum, but ruled out the possibility of an organised terrorist attack.

“Four ragpickers were killed and several were injured in the blast. It appears to be an explosion of a crude bomb,” said city police commissioner Gautam Mohan Chakraborti. “But there is no need to panic.” Indian cities have been hit by a wave of bombings in recent weeks.—AFP
