In the days since, tensions have risen dangerously between India and Pakistan, which have fought two of their three wars over Kashmir.

The Pakistani government said that if India followed through on a threat to block rivers it would take it as “an act of war.”

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.
