India and Pakistan engaged in the most intense fighting in decades with four days of escalating conflict that included fighter jets, missiles and drones packed with explosives. It ended almost as abruptly as it began.

India and Pakistan early Monday agreed to resolve a week of strikes and clashes with a ceasefire that does not permit “a single shot” or any other type of aggressive action. Both sides must also “consider immediate measures to ensure troop reduction” from their borders.
