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.

NEW DELHI — India and Pakistan agreed to an immediate ceasefire on Saturday, halting days of clashes that killed dozens of people and pushed the nuclear-armed neighbors to the brink of war.

India-Pakistan conflict escalated with missile exchanges and retaliatory strikes. US-brokered ceasefire efforts faced challenges with China's discontent over exclusion from mediation, leading to brief ceasefire violations before tension eased.
