More than half of the tourist destinations in India's insurgency-torn Kashmir region have been closed to the public from Tuesday, according to a government order reviewed by Reuters, in a bid to tighten security after last week's attack on holiday-makers.

India's Prime Minister Narendra Modi says the gunmen behind a terrorist attack on tourists in the Kashmir region "will not be spared!"

Kashmiris have denounced last week’s deadly militant assault on tourists in Pahalgam but fear they will be caught in the widening Indian clampdown.
