NEW DELHI (AP) — India has only “paused” its military action and will “retaliate on its own terms” if there is any future terror attack on the country, Prime Minister Narendra Modi said Monday in his first public comments since a U.S.-brokered ceasefire over the weekend.

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.

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