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.

The ceasefire had been expected to bring a swift end to weeks of escalating clashes triggered by the mass shooting of tourists last month that India blames on Pakistan.

Pakistan's army said on Tuesday that more than 50 people were killed in last week's military clashes with India which ended in a ceasefire agreed by the nuclear-armed neighbours, restoring peace to their border.

In such a scenario, where Pakistan faces an existential threat, or believes that its territory is about to be overrun, it may decide to “go nuclear”—even at the risk of self-destruction. The latest test of this pattern arose in the aftermath of a terrorist attack in Indian-Administered Kashmir on April 22.

The Pakistan Super League is set to resume this weekend after a ceasefire between Pakistan and India. “Let the aura take over as we unite and celebrate the spirit of cricket," he posted. Pakistan and India agreed to a truce last Saturday after talks to defuse their most serious military confrontation in decades.

The military operations chiefs of India and Pakistan spoke by phone on Monday, the Indian army said, as New Delhi reopened airports and shares rose in both countries following a ceasefire that paused days of intense fighting last week.
