The Pakistani military says Indian troops have attacked an army post in Pakistan-administered Kashmir, killing one soldier and wounding another.
They say troops are still exchanging gunfire in the area.
The BBC reports a spokesperson for the Indian army accused Pakistan of firing mortar shells into Indian territory.
Kashmir is claimed by both nations in its entirety and has been a flashpoint between them for more than 60 years.
Exchanges are not uncommon but rarely result in fatalities.
