WASHINGTON—Nuclear-armed rivals India and Pakistan have agreed to a ceasefire following U.S.-led talks to end an intensifying military confrontation, President Donald Trump announced in a post on his Truth Social media platform Saturday morning.

The ceasefire deal follows weeks of clashes, missile and drone strikes across their borders that were triggered by a gun massacre of tourists last month that India blames on Pakistan, which denies the charge. Dozens of civilians have been killed on both sides.
