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

Twenty-six men were killed and 17 were injured when suspected militants opened fire at tourists in India's Jammu and Kashmir territory, police said.

India said on Monday it had responded to 'unprovoked' firing from Pakistan along the de facto border for the fourth consecutive night, as it deepens its search for militants in the region following last week's deadly attack on tourists in Kashmir.
