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 and Pakistan early Monday agreed to resolve a week of strikes and clashes with a ceasefire that does not permit “a single shot” or any other type of aggressive action. Both sides must also “consider immediate measures to ensure troop reduction” from their borders.
