Iran’s foreign minister is in Pakistan to try and mediate in the escalation between Islamabad and New Delhi after last month’s deadly attack on tourists in the Indian-controlled section of Kashmir.

The April 22 terrorist attack in Kashmir inflamed a long-simmering conflict that could boil over into military confrontation.

The Kremlin said on Monday that it was following with great concern the tense atmosphere at the India-Pakistan border in Kashmir, where suspected militants killed at least 26 people in attack last week.
