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

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.

The ceasefire has halted what some analysts say was the most serious fighting between the two countries since a 1971 war. But India's recent suspension of a key water-sharing treaty remains in place.
