India and Pakistan have agreed to an immediate U.S.-mediated ceasefire ending the conflict between the two nuclear-weapon states, which has sparked concerns about the wider war.

U.S. President Donald Trump announced the ceasefire for the first time after 48 hours of diplomacy between India and Pakistan, apparently by U.S. Secretary of State Marco Rubio and Deputy resident JD Vance.

Trump said in an article on his Truth Social Platform: "After the United States mediated a long talk, I am pleased to announce that India and Pakistan have agreed to a full and direct ceasefire. Congratulations to both countries on their use of common sense and great wisdom. Thank you for your attention!"

The ceasefire was later confirmed in an article on X by Pakistan’s Deputy Prime Minister and Foreign Minister Ishaq Dar, who said the ceasefire would “be effective immediately.”

Indian Foreign Minister Vikram Misri said the head of military operations from both countries spoke on Saturday afternoon.

"With their agreement, both sides will cease all shooting and military operations on the land, as well as the air and the ocean. Both sides have directives to make this understanding effective." Misri added that senior military officials will speak again on May 12.

Rubio said the deal follows extensive negotiations with Indian and Pakistani Prime Ministers Narendra Modi and Shehbaz Sharif, among other senior officials.

Rubio said on X: "I am pleased to announce that the Indian and Pakistan governments have agreed to an immediate ceasefire and begin negotiations on a range of issues on neutral locations."

He added: "We praise Prime Minister Modi and Sharif for their wisdom, prudence and politicians in choosing the path to peace."

The ceasefire comes after India and Pakistan’s cross-border missile strikes targeting major military targets on Saturday, the most important escalation in decades between the two countries.

Earlier, India accused Pakistan of launching strikes on dozens of air bases and military headquarters on Saturday using long-range weapons, drones and fighters. The allegations come hours after Pakistan said India launched six ground-oriented air missiles targeting Pakistan’s three most important military bases early Saturday morning.

Shortly thereafter, Pakistani officials confirmed that they had begun a counterattack against India, in the name of Operation Bunyan ul Marsoos, a sentence from the Quran that roughly translated into a “lead wall.”

The claims of missile strikes on military targets within India and deep in Pakistan are considered a worrying escalation of hostilities.

Pakistan first attacked on Saturday, according to Indian Army spokesman Col Sofiya Qureshi. In a press conference, Indian troops accused Pakistan of attacking 26 locations in India, including the Pathankot military airport in Punjab, Srinagar airport and the Udhampur air base in Kashmir managed by India, as well as a "pathetic and timid" attack on the civilian infrastructure.

"The Indian armed forces successfully neutralized these threats," Qureshi said, but added that some damage was caused to the equipment and personnel of the four air bases. Foreign Minister Vikram Misri said the Pakistani media claims that the destruction of the air force and advanced weapons systems during the strike was "a heavy lie, misinformation and propaganda".

Indian troops accused Saturday of attacks on Pakistani military bases in retaliation for high-speed missiles fired at several air bases in Punjab at around 2 a.m. "In a rapid and calibrated response, the Indian armed forces carried out precise attacks on only identified military targets," Qureshi said.

In the hours following the missile strike, both India and Pakistan said they would promise to relegate if the other party agreed to stop the attack.

Pakistan's Deputy Prime Minister and Foreign Minister Ishaq Dar told local media that if India stops here "we will consider stopping here" while the relegated ball is in the Indian court. India also said it has been committed to "non-propaganda" if Pakistan reciprocated services.

However, Indian troops claimed that Pakistan was still mobilizing its troops, which they believed was further aggression.

Pakistan's version of the event is different from India. Military spokesman Ahmed Sharif Chaudhry, on a broadcast on the state television address at around 3.30 a.m., claimed that India had first attacked, using fighter jets to launch ground-oriented air missiles at Nur Khan, Murid and Shorkot military bases. He said "most" of Indian missiles were intercepted by air defense systems.

Nur Khan Airbase is in Rawalpindi, where the military has its headquarters, about six miles from Islamabad, the capital of Pakistan. After the strike, Pakistan closed the airspace.

The strike against Nur Khan has caused massive panic in densely populated areas. Videos shared on social media on site showed flames and smoke rolling into the night sky and residents ran to the streets. "The loud explosion woke everyone up. It was horrible and everyone was still panicking," said a nearby resident.

The battle this week's battle was inflamed for the first time Wednesday after Indian missiles hit nine locations in Pakistan and killed 31 people. India has said the strikes are in response to the Kashmir attacks managed in India late last month, in which militants killed 25 Hindu tourists and a guide who blamed Pakistan-backed extremists.

The situation escalated further after India accused Pakistan of conducting drone attacks for two consecutive nights. India claims to have intercepted more than 400 drones targeting cities, military bases and places of worship on Thursday

In retaliation, India said it had launched four drone strikes in Pakistan, directly targeting military defense infrastructure.

The ceasefire of the U.S. brokerage ended concerns about the spiral cycle of escalating and wider wars, which attracted international attention. Earlier on Saturday, the G7 called on both countries to exercise "maximum restrictions."
