Nuclear-armed neighbours India and Pakistan agreed to a ceasefire on Saturday after US pressure and four days of fighting, but within hours explosions rang out in border cities and towns and India accused Pakistan of violating the pact.
Artillery fire and attack drones were witnessed in Jammu and Kashmir, the centre of much of the fighting, while blasts from air-defence systems boomed in cities under blackout, similar to the previous evening, according to authorities, residents and Reuters witnesses, according to Retuers.
Indian Foreign Secretary Vikram Misri told reporters that Pakistan had violated the understanding arrived at by the two countries earlier in the day, and that the Indian armed forces had been instructed to "deal strongly" with any repetition.
"We call upon Pakistan to take appropriate steps to address these violations and deal with the situation with seriousness and responsibility," Misri told a media briefing.
In response, the foreign ministry of Pakistan said the country was committed to the ceasefire and blamed India for the violations. "Our forces are handling the situation with responsibility and restraint," it said.
The ministry also called on troops on the ground to exercise restraint and said that any issues in the implementation of the ceasefire should be addressed through communication at appropriate levels.
Pakistan's military spokesperson did not immediately respond to requests for comment.
The fighting has 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 briefly fears that nuclear arsenals might come into play as Pakistan's military said a top body overseeing its nuclear weapons would meet.
But the defence minister said no such meeting was scheduled, hours after a night of heavy fighting in which the two countries targeted each other’s military bases and the combined civilian death toll rose to 66.
"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!"
Misri had earlier said the chiefs of the two countries' military operations had spoken to each other and agreed that all fighting would stop at 5 p.m. Indian time (1130 GMT).
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."
