| 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 scavengers 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. About 50 people died last weekend in 20 blasts in western Ahmedabad city, a day after a string of bombs went off in the southern high-tech city of Bangalore. |
