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.

Hours after reaching a ceasefire agreement, multiple explosions were heard in two cities in Indian-controlled Kashmir. India's foreign secretary later said there had been "repeated violations" of the deal.

India and Pakistan have agreed to an immediate ceasefire after days of military escalation, deadly cross-border attacks, accusations and counter accusations, had raised acute concerns that the two nuclear-armed neighbours would engage in an all-out war for the fifth time since 1947.
