NEW DELHI, March 14 (UPI) -- Police on Friday defused at least six explosive devices found at the main railway station in New Delhi a day after an explosion killed 12 people on a train in Bombay.
The bombs were found in unattended baggage, authorities said. Security in both cities has been increased to prevent further incidents.
No one knows who is behind the attacks.
A passenger spotted the bombs in an unattended bag near a taxi stand, Railway Police Deputy Commissioner R S Ghuman said. He told the Press Trust of India news agency that no timers were attached to the devices.
New Delhi police were flooded with scores of calls from people complaining of unidentified objects seen at several places but all the calls turned out to be hoaxes.
The Indian capital has been on a high alert after Thursday's train explosion in Bombay that killed 12 people, and left at least 80 others wounded. Police checkpoints are in place elsewhere, according to authorities.
Authorities said the bomb went off just as the train was pulling into the Mulund station during the busy evening rush hour
Witnesses said the explosion tore the roof off a first-class car that had been reserved for female passengers. Many of the injured suffered trauma to their upper bodies, witnesses said.
At least seven of the dead were women, including a police officer.
Bombay Police Commissioner R.S. Sharma said the bombing was the work of terrorists, but he didn't elaborate.
This was the fourth bombing to rock Bombay since March 2002 and comes 10 years after the city was struck by a series of bombings that killed 257 people and wounded 713 others.
