India and Pakistan agreed to an immediate ceasefire on Saturday, unexpectedly halting the worst fighting in decades between the nuclear-armed neighbors, just when their tit-for-tat strikes appeared to be spiraling out of control.

President Donald Trump announced that the two countries had reached a "full and immediate ceasefire" following a series of escalating attacks.
