GAUHATI, India -- A group of rebels ambushed a military convoy in India's insurgency-wracked northeast on Thursday, killing at least 10 soldiers and wounding 12 others in the latest major attack in the region in recent months, police said.

The ambush occurred as the convoy was on its way from a small town to Imphal, the capital of Manipur state, a police officer said on condition of anonymity because he was not authorized to talk to reporters.

The state, which borders Myanmar, has several active militant groups. None immediately claimed responsibility for the attack.

No other details were immediately available.

In April, insurgents armed with automatic weapons fired at two trucks carrying Indian paramilitary soldiers in neighboring Nagaland state, killing eight of them.

The mountainous region, known for its natural beauty, has been battling insurgencies for decades.

Most of the main rebel groups in Manipur state are not engaged in cease-fire talks with the Indian government, unlike those in other remote northeastern states.
