Russian Foreign Minister Sergei Lavrov spoke to his Pakistani counterpart on Sunday and offered Russia's help in resolving tensions between Pakistan and India over Kashmir, the Foreign Ministry said.

The United States is stepping up pressure on India and Pakistan to avoid conflict in Kashmir after a tourist massacre in an Indian-administered area of the divided territory last week.

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".
