The Indian military says Pakistani soldiers fired at Indian posts all along the highly militarized frontier in disputed Kashmir as tensions flare over attack on tourists.

Armed police and soldiers searched homes and forests for militants in Indian Kashmir on Friday and India's army chief reviewed security there after the killing of 26 men at a tourist site - the worst attack on civilians in nearly two decades.

The clash took place just days after a terror attack killed 26 people on the Indian side of the disputed region, raising tensions between the two nuclear-armed nations.
