Police in India say they have detained 10 people in connection with a series of explosions that rocked New Delhi Saturday, killing at least 55 people and injuring more than 150 others.
The arrests came hours after four near-simultaneous blasts ripped through the Indian capital, all in areas crowded with people enjoying Diwali, the annual Hindu festival of lights. Indian Prime Minister Manmohan Singh denounced the bombings as a terrorist act. Officials say he has cut short a trip to Calcutta to return to the capital to chair an emergency meeting with security officials. Police have stepped up security and ordered all markets in the city closed. Officials say the powerful explosive RDX was used in the attacks, which occurred as Indian and Pakistani officials began talks on opening the heavily militarized Line of Control in disputed Kashmir to help aid victims of this month's massive earthquake. No one has yet claimed responsibility for the attacks.
