There have been repeated violations, says Vikram Misri, the highest official at the Indian Foreign Ministry, at a brief press conference, reports BBC.
Misri says further that the Indian military is striking back against a "border violation" and urges Pakistan to take necessary measures.
The allegations are rejected by Pakistan's Information Minister Ataullah Tarar.
Breaches of the ceasefire from our side are ruled out, he says to the Pakistani news channel Geo News.
Pakistan's Foreign Ministry states that it "still stands firm" on the ceasefire and makes counter-allegations. Despite "the violations committed by India in certain areas", Pakistan's military has reacted "responsibly and with restraint", according to the statement.
It says further that "eventual issues" should be "solved through communication on suitable levels".
Explosions and Power Outages
On Saturday afternoon, reports emerged of explosions and subsequent power outages in the major cities of Srinagar and Jammu, according to AP. There were also reports of drones and shelling at several locations in the border area between the two nuclear powers.
There is no ceasefire," wrote Omar Abdullah, a leading Indian politician in the region of Jammu and Kashmir, on X.
Inhabitants in parts of the Indian states bordering Pakistan, such as Punjab and Rajasthan, have been urged by the authorities to stay indoors after drones were sighted, writes The Times of India.
"Congratulations to both"
The developments come just hours after the United States President Donald Trump and then India and Pakistan announced that the countries had agreed on a ceasefire.
The talks between the parties are said to have been led by the US Foreign Minister Marco Rubio, who states that the countries have agreed on continued talks on neutral ground.
"Congratulations to both countries for using sound judgment and good intelligence", wrote Trump on Truth Social.
Terror Attack Triggered
The triggering factor for the increased tensions over the past weeks was a massacre of tourists on April 22 in the Indian-controlled part of the long-disputed Kashmir region. India accuses Pakistan of having given its support to the perpetrators, which is denied by the country.
Over the past few days, cross-border shelling has claimed dozens of lives on both sides, according to the countries' respective authorities, including many civilians.
