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.

A fragile ceasefire was holding between India and Pakistan on Sunday, after hours of overnight fighting between the nuclear-armed neighbours, as U.S. President Donald Trump said he will work to provide a solution regarding Kashmir.
