Security forces in the Indian capital, New Delhi, are on high alert Sunday one day after a series of bomb blasts rocked the city, killing at least 61 people and injuring more than 150 others.
Authorities declared a state of emergency, closed down all marketplaces in the city and appealed to citizens to stay away from public areas. Armed police set up roadblocks around the capital.
Saturday's blasts struck two markets and a bus as crowds of people were preparing for Diwali, the annual Hindu festival of lights. Police say they have detained 10 people in connection with the attacks.
An unknown group calling itself Inquilab contacted a news agency in Indian Kashmir to claim reponsibility for the blasts. But it was not clear if the claim was genuine.
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.
