Islamabad, Pakistan - Islamabad, Pakistan (AP) - The April 22 tourist massacre has brought India and Pakistan to war, marking the biggest collapse of relations since 2019.

Conflicts between India and Pakistan are not uncommon, and the two countries have regularly engaged in wars, conflicts and conflicts since their independence from British India in 1947.

The difference between this escalation is the frequency and intensity of strikes and retaliation.

Although the United States has said it will not intervene, it is now helping to "start constructive negotiations" between India and Pakistan to avoid future conflicts. However, the restrictions appealing to the international community have not yet had any impact.

Here is a timeline of how the latest conflict unfolds:

The gunmen shot and killed at least 26 tourists in the Pahalgam resort in India-controlled Kashmir, a major shift in regional conflicts that largely survived civilians. The unidentified gunman also suffered another 17 injuries. India accused Pakistan-backed group called the Kashmir Resistance movement of claiming the attack.

Survivors told the Associated Press that the gunman asked if people were Hindus and then opened fire.

India lowered diplomatic ties, closed its sole border crossing point in its functional location, and suspended a key water sharing treaty that survived two wars and had a major border skirmish between the two countries.

India launched a raid for Pahalgam attackers. Pakistan denies participating in the attack.

India and Pakistan canceled each other's national visas, leaving them a deadline. In retaliation, Pakistan closed its airspace for all Indian-owned or Indian-operated airlines and suspended all trade with India, including traveling to and from any third country.

Government ministers on both sides have hinted that the dispute could escalate into military action.

India said its troops exchanged fires with Pakistani soldiers on the line of control, and the de facto borders separate the disputed Kashmir region.

Pakistan warned that it could suspend a deal to establish control, a major and worrying step. The United Nations urges both sides to "exercise their greatest restraint."

Pakistani Prime Minister Shehbaz Sharif has vowed that his government will "go out all out" to stop or divert the flow of water.

Iran provides mediation, while Trump says he hopes they can resolve the differences. He told the reporter on Air Force One: "There is a lot of tension between Pakistan and India, but there will always be."

Indian-controlled Kashmir authorities temporarily closed dozens of resorts in the scenic Himalayas following a fatal attack on tourists.

Forces from both countries exchanged fires on the control line for the fifth consecutive night.

Pakistan's Information Minister Attaullah Tarar said his government has "reliable intelligence" and India intends to take military action against Pakistan within the next 24 to 36 hours.

U.S. Secretary of State Marco Rubio convened senior officials from India and Pakistan to undermine the crisis. In a call with India, U.S. State Department spokesman Tammy Bruce said Rubio was sad about Pahalgam's killing and reiterated the United States' "commitment to cooperate with India and India against terrorism."

Pakistan said Rubio stressed the need for both sides to "continue to work together for peace and stability" in South Asia.

Pakistan has tried a ballistic missile with a range of 450 kilometers (about 280 miles). Missiles are not launched into the Indian border areas; they are usually sent into the Arabian Sea or the deserts of the southwestern Balluchistan province.

India suspended the exchange of all mail from Pakistan via air and ground routes and prohibited the direct and indirect import of goods from its neighbors. It also bans Pakistan-owned ships from entering the port and prohibits Indian-signed ships from visiting Pakistani ports.

India fired missiles at Pakistan, which called the strike a "act of war" and vowed to take revenge for those who died in the pre-dawn attack.

In Kashmir, which is managed by Pakistan and in the country's Punjab province, the missiles killed 31 people, including women and children. The Indian Ministry of Defense said the strikes targeted at least nine locations "planned terrorist attacks on India."

Pakistan claims it defeated Indian fighter jets several times.

Pakistani military said India fired attack drones at Pakistan, killing at least two civilians. Meanwhile, India accused its neighbors of trying to attack themselves and admitted to air defense systems targeting competitors.

India evacuates thousands of people from villages near the highly militarized border of Kashmir. In northern and western India, flights are still suspended at twelve airports.

Punjab, Pakistan, announced the immediate closure of all schools and other educational institutions.

India suspended its largest domestic cricket match after military tensions with Pakistan escalated. Pakistan initially said it would move its domestic T20 tournament to the United Arab Emirates due to the crisis, but later said it would only postpone the match.

Several states in North India and the western region closed schools and other educational institutions.

US Vice President JD Vance said the potential war between India and Pakistan would be "unrelated".

Indian troops said drones were seen in 26 locations in Indian states bordering Pakistan and Indian-controlled Kashmir, including the main city of Srinagar. It added that the drone was tracked and involved.

Groups in seven countries (or G7) urged India and Pakistan to "maximum restrictions", warning that further military escalation posed a serious threat to regional stability.

Pakistan said India has launched missiles at air bases within the country and is undergoing a retaliation strike. Indian missiles targeted the Nur Khan Air Base in Rawalpindi, the garrison city of Rawalpindi, the Murid Air Base in Chakwar City and the Lafiki Air Base in Jabang District, Punjab Province, in eastern Punjab Province, according to a chief spokesman for the Pakistan Army.

Pakistan said it had launched missiles at Indian military positions.

Residents of Indian-controlled Kashmir reported loud explosions in several places in the region, including Srinagar, Jamu and the garrison town of Udampur.
