As tensions ratcheted up over the last week of fighting, Pakistan did not consider deploying nuclear warheads to strike India, the country’s foreign minister Ishaq Dar told CNN on Monday.

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

A fragile ceasefire was holding between India and Pakistan on Sunday, after hours of overnight fighting between the nuclear-armed neighbours, as U.S. President Donald Trump said he will work to provide a solution regarding Kashmir.
