MUZAFFARABAD, Pakistan (Reuters) - The government of Pakistan-administered Kashmir has closed all religious seminaries in the region for 10 days, officials said on Thursday, citing fears they would be targeted by Indian strikes following a deadly attack on tourists in Indian Kashmir.

The US has urged India and Pakistan to work together to "de-escalate tensions" after a deadly militant attack in Indian-administered Kashmir last week killed 26 civilians. Secretary of State Marco Rubio held separate talks with India's foreign minister and Pakistan's prime minister on Wednesday and called on them to "maintain peace and security in South Asia".

Indian Prime Minister Narendra Modi has vowed to pursue the assailants behind last month's attack on tourists in Kashmir to the "ends of the earth". India says two of the three "terrorists" involved in the attack were from arch-enemy Pakistan,
