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.

The frontier between arch-foes India and Pakistan was peaceful and had the "first calm night in recent days", the Indian army said Monday, after a surprise weekend ceasefire.

The military operations chiefs of India and Pakistan held talks by phone on Monday evening, broadcaster CNN-News18 said, two days after the nuclear-armed neighbours reached a ceasefire agreement following intense fighting last week.
