Suspected Maoist rebels blew up a police van in eastern India today, killing at least 11 police.
Officials say the attackers detonated a land mine targeting a police patrol in West Singhbhum district, about 100 miles (160 km) east of Ranchi, the capital of Jharkhand state.
Six other police officials were critically injured in the attack.
Sources say about 30 people were in the police van at the time, but no details about the others were immediately available. The area where the attack took place is remote and densely forested.
The rebels are known as Naxalites after Naxalbari, a village in West Bengal state where the movement was born in 1967, and say they are inspired by Chinese communist revolutionary leader Mao Zedong.
The rebels have been fighting for more than three decades in several Indian states, demanding land and jobs for agricultural workers and the poor.
