Police detain 6 in attacks in India that killed 77

Guwahati: Indian police detained six people on Saturday after a little-known Islamist group claimed responsibility for bombings that killed 77 people in Assam.

Police said two cars and mobile phones used to detonate bombs in Assam had been traced to four men while the remaining two were picked up for possible links with the attackers.

A police officer said two of three cars used as bombs in Guwahati had been identified.

"One of the vehicle owners has been picked up for questioning," said Bhaskar Jyoti Mahanta, an inspector general of police.

The Islamic Security Force-Indian Mujahideen sent a mobile text message to a local television station claiming responsibility for the bombings.

Police also were talking to a lawyer who said he had seen two men park a car near one of the blast sites in Guwahati and leave nervously. Police were preparing sketches of the pair.
