Tensions between India and Pakistan have escalated further after a top Pakistani official claimed early Wednesday to have “credible intelligence” that New Delhi will carry out a military action against Islamabad within the next two days.

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".

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.
