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.

Pakistan accused India on Wednesday of planning an imminent military strike using a terror attack that killed 26 Indian tourists in the disputed Kashmir region last week as a "false pretext" to hit out at its neighbor.
