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

The arch rivals were involved in intense firing for four days, the worst in nearly three decades, with missiles and drones being fired at each other¡¯s military installations and dozens of people killed.

A ceasefire agreement was reached after diplomacy and pressure from the United States, but within hours, artillery fire was witnessed in Indian Kashmir, the center of much of the fighting.
