Ten police personnel and a driver were killed in a blast carried out by Naxalites in Chhattisgarh's Dantewada district on Wednesday, officials said.
The incident took place under Aranpur police station limits when a team of the state police's District Reserve Guard (DRG) was returning after an anti-Naxalite operation, a senior official said. The area is located around 450 km from state capital Raipur.
Naxalites blew up the mini-goods van in which the security personnel were travelling by using an Improvised Explosive Device (IED), police sources said.
Further details were awaited.
