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.

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.

India's foreign minister said he has told Secretary of State Marco Rubio that perpetrators of the deadly attack in Kashmir last week should be brought to justice, as the U.S. sought to calm tensions between nuclear-armed India and Pakistan.
