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.

India exchanged a Pakistani paramilitary fighter for a border security guard that Pakistan had held for weeks. Each officer had been detained before the countries’ military skirmish started.
