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

By Aftab Ahmed, Shivam Patel and Saurabh Sharma JAMMU, India/ISLAMABAD (Reuters) - 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.

Civilian flights were returning to normal, and stocks jumped in both nations, signs of confidence that the agreement to halt fighting was holding.
