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.

Both nations have ceased hostilities since the announcement of the ceasefire on Saturday but say they remain vigilant.

Pakistan accused India of launching air-to-surface missiles that targeted at least three bases. Soon after, Pakistani officials said retaliatory action against Indian bases had begun.
