India and Pakistan agreed to a ceasefire Saturday after U.S.-led talks to end the most serious military confrontation between the nuclear-armed rivals in decades but accused each other of violating the deal just hours later.

The first word of the truce came from U.S. President Donald Trump, who posted on his Truth Social platform that he was pleased to announce that India and Pakistan had agreed to a full and immediate ceasefire. “Congratulations to both Countries on using Common Sense and Great Intelligence. Thank you for your attention to this matter!”

Pakistan ceasefire resulted from US mediation appears to have been unequivocally refuted by the Indian government, which said that the ceasefire was negotiated directly between the two nations.
