U.S. President Donald Trump said on Saturday that India and Pakistan had agreed to a “full and immediate ceasefire” after a fourth day of strikes and counter-strikes against each other’s military installations.

Pakistan’s foreign minister also said both countries had agreed to a ceasefire “with immediate effect”.

“After a long night of talks mediated by the United States, I am pleased to announce that India and Pakistan have agreed to a FULL AND IMMEDIATE CEASEFIRE. Congratulations to both Countries on using Common Sense and Great Intelligence,” he said in a post on Truth Social.

The announcement came on a day when fears that the countries’ nuclear arsenals might come into play spiked as the Pakistan military said a top military and civil body overseeing its nuclear weapons would meet.

But the Pakistani defence minister later said no such meeting was scheduled.
