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".

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".

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.
