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.

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.

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