At least 20 soldiers have been killed and 15 injured in an attack on a troop convoy in north-east India.
The ambush occurred in the state of Manipur as the convoy made its way to Imphal, the state capital.
The region's deadliest in years, the attack is thought to be a retaliation for the death of a woman who soldiers are accused of killing on Monday.
Authorities in Manipur have struggled for years with an insurgency involving several militant groups.
Police said rebels used rocket-propelled grenades and assault rifles to target the soldiers.
