The neighboring countries exchanged fire for several days after India's missile attack on Pakistan before reaching a ceasefire on Saturday.

The truce came after several days of the countries’ most expansive fighting in decades. One Indian official said the country would “deal strongly” with any violations.

Pakistan and India accused each other of violating a ceasefire deal made hours earlier on Saturday following U.S.-led talks aimed at ending the most serious military confrontation between the nuclear-armed rivals in decades.
