Nuclear-armed neighbours India and Pakistan agreed to a ceasefire on Saturday after US pressure and diplomacy, announcing a sudden stop to a conflict that had seemed to be spiralling alarmingly.

But within hours, violations were reported from the main cities of Indian Kashmir, the territory that had borne the brunt of four days of fighting.

Latest report from Azad Jammu and Kashmir said explosions were head in Bhimber district. CNN, citing government sources, said India had attacked from the other side of the Line of Control and dozens of explosions were heard.

Local sources said explosions were also heard in Bahwalpur.

Earlier, Reuters reported that blasts were heard in Srinagar and Jammu, and projectiles and flashes were seen in the night sky over Jammu, similar to the events of the previous evening, according to authorities, residents and Reuters witnesses.

Military spokespeople in both countries did not immediately respond to requests for comment.

The fighting had been the worst between the old South Asian enemies in nearly three decades and threatened to erupt into a full-scale war in one of the world’s most volatile and densely populated regions.

There were brief fears that nuclear arsenals might come into play as Pakistan’s military said a top body overseeing its nuclear weapons would meet.

“Pakistan and India have agreed to a ceasefire with immediate effect,” Foreign Minister Ishaq Dar posted on X. “Pakistan has always strived for peace and security in the region, without compromising on its sovereignty and territorial integrity!”

The Indian foreign secretary said the two countries’ military chiefs had spoken to each other and agreed that all fighting would stop at 5pm, without using the word “ceasefire”.

US President Donald Trump posted: “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.”
