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 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.

India said on Saturday it had banned the import of goods coming from or transiting via Pakistan and barred Pakistani ships as tensions rise between the nuclear-armed neighbours in the wake of a deadly attack on tourists in the disputed Kashmir region.
