Authorities in Indian-controlled Kashmir have temporarily shut more than half of tourist resorts in the scenic Himalayan region following a deadly attack on tourists.

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.

Authorities in Indian-administered Kashmir have demolished the houses of at least 10 alleged militants and detained more people for questioning as investigations continue into last week's killings of 26 people.
