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

Dozens of Pakistani nationals living in India are heading to the main land crossing between India and Pakistan, following New Delhi's decision to order almost all Pakistani citizens to leave the country after last week's deadly attack in Indian-controlled Kashmir.

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