Pakistan had no plans on deploying nuclear warheads to strike India over the last week of fighting, the country’s foreign minister Ishaq Dar told CNN Monday.

Pakistani officials have said Saturday’s ceasefire with India reestablished deterrence. But New Delhi insists the rules of engagement have irrevocably changed.

India accused Pakistan of backing the militants who carried out the massacre, a charge Islamabad denied. After Wednesday's strikes in Pakistan, both sides exchanged heavy fires along their de facto border in the disputed territory of Kashmir. Dozens of civilians were killed on both sides in heavy shelling, the two countries said.
