The ceasefire follows weeks of clashes that were triggered by a gun massacre on tourists last month that India blames on Pakistan. The first word on the truce came from U.S.

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.

The sudden announcement of a U.S.-brokered ceasefire followed four days of steady escalation between India and Pakistan and mixed signals from Washington.
