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.

Civilian airports were reopened and stocks jumped in both nations, signs of confidence that the agreement to halt the most alarming fighting in decades was holding.
