At least five bombs exploded in quick succession in crowded markets and streets in the heart of India's capital New Delhi Saturday, killing at least 30 people and injuring a 100 others. The Indian Mujahideen militant group, which says it has carried out several major attacks in recent months, sent an e-mail to local television stations claiming responsibility for the attacks. Police and witnesses said two went off in dustbins in and around Connaught Place, a shopping and dining area popular with tourists and locals in the center of the city. Others exploded in busy markets around the city, within minutes of each other. Police say they are questioning a 12-year-old boy who may be able to provide clues and a description of a suspect. Delhi Police Commissioner Y.S. Dadwal told reporters, that two more bombs were found and defused. “They do not seem to be of very high intensity.” Police say the Indian Mujahideen is an offshoot of the banned Students' Islamic Movement of India. One bomb exploded in a newly constructed park in the center of the Connaught Place roundabout, built above one of the main stations of the Delhi Metro. Another went off in a dustbin near a metro station entrance on a main arterial road leading into the area, housing the offices of several foreign banks and multinational companies. “Around 6:30 P.M. we heard a very loud noise, then we saw people running all over the place,” said Chanchal Kumar, a witness whose shirt was soaked in blood of several victims he had helped shift into ambulances.
