SRINAGAR, India (AP) — A hand grenade has exploded outside a paramilitary bunker in the disputed Himalayan region of Kashmir, injuring at least five Indian soldiers.

Police blamed anti-India militants for the attack Sunday in Sopore town. No rebel group has claimed responsibility, and no suspects have been arrested.

Sopore police chief Imtiyaz Hussain says one of the wounded soldiers is in critical condition.

Kashmir is divided between India and Pakistan. The Indian-administered region remains tense after authorities suppressed a separatist uprising that began in 1989. About 68,000 people died in the insurgency and ensuing crackdowns.
