India’s moves to punish Pakistan after accusing it of backing the attack have driven tensions between the nuclear-armed rivals.

U.S. Secretary of State Marco Rubio urged India and Pakistan to work with each other to de-escalate tensions after last week's Islamist militant attack in India-administered Kashmir, the State Department said on Wednesday.

Pakistan's government has said it has "credible intelligence" that India intends to launch military action soon after days of escalating tensions.
