India accused Pakistan of violating a ceasefire hours after the two countries announced it on Saturday, while Pakistan has denied the accusation.
According to Indian media reports, loud blasts were heard in Indian-controlled Kashmir on Saturday evening, and a blackout was enforced later in some areas.
Indian Foreign Secretary Vikram Misri told a press briefing in the evening that the Indian armed forces were responding to ceasefire violations by Pakistan.
In response, Pakistan's Federal Minister for Information and Broadcasting Attaullah Tarar told local media that there had been no violations of the agreement, dismissing relevant Indian media reports as groundless.
Earlier in the day, Pakistan and India announced that they had agreed on a ceasefire.
The announcement came following four days of military strikes on each other.
Pakistan's Deputy Prime Minister and Foreign Minister Ishaq Dar said on social media that Pakistan and India have agreed to a ceasefire with immediate effect.
It is a "full-fledged" and "not partial" ceasefire, Dar said in an interview.
Pakistan has always striven for peace and security in the region, without compromising on its sovereignty and territorial integrity, he said in the social media post.
The Pakistan Civil Aviation Authority said on Saturday that Pakistan has fully reopened its airspace for all types of flight operations, assuring travelers that the aviation network is now functioning normally.
Misri announced at a press conference on the day that New Delhi and Islamabad have agreed to observe a ceasefire and stop military actions.
According to Misri, the two sides agreed to cease all land, sea, and air exchanges of fire and military actions starting from 17:00 Indian Standard Time (11:00 GMT) on Saturday.
The top military leaders of the two countries will speak again on Monday, Misri added.
After the deal was reached, Pakistani Prime Minister Shehbaz Sharif thanked the international community for facilitating this outcome and expressed hope for resolving issues through peaceful dialogue with India.
On Wednesday, India launched airstrikes on Pakistani targets to avenge last month's killing of 26 people by gunmen in Pahalgam town, about 89 km east of Srinagar, the summer capital of Indian-controlled Kashmir.
India blamed Pakistan for being behind the incident, a charge denied by Pakistan.
The situation along the Line of Control dividing Kashmir had been tense as troops of India and Pakistan deployed on both sides of the ceasefire line were engaged in an exchange of fire and artillery.
