A hitherto unknown militant outfit, Inquilab group, claimed responsibility on Sunday for the three serial blasts that ripped through the capital, killing 61 and injuring nearly 200 people.

A caller identifying himself as Ahmad Yaar Gaznavi, a spokesman of Inquilab group, claimed that the activists of the outfit had carried out the bomb explosions in Delhi. "Our activists are involved in the three explosions", he said, adding that it was in response to the activities of Indian security forces in Jammu and Kashmir.
