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 and Pakistan engaged in the most intense fighting in decades with four days of escalating conflict that included fighter jets, missiles and drones packed with explosives. It ended almost as abruptly as it began.
