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.

India blames Pakistan for an attack on its tourists and threatens to disrupt Pakistani water supplies. Islamabad says that move would be an act of war.
