The United States is stepping up pressure on India and Pakistan to avoid conflict in Kashmir after a tourist massacre in an Indian-administered area of the divided territory last week.

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.

U.S. Secretary of State Marco Rubio called senior officials in India and Pakistan in an effort to defuse the crisis that followed last week’s deadly attack in Kashmir, the State Department said.
