Pakistani Foreign Minister Ishaq Dar made the announcement on Sunday.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes attack targeting military and government sites, officials said.
Ayatollah Ali Khamenei was among those killed in Tehran on the first day of strikes, with his son Mojtaba Khamenei later chosen to succeed him. Iran has responded with missile and drone attacks targeting Israel, regional U.S. bases and multiple Gulf nations. Iran is also attempting to block some shipping traffic through the Strait of Hormuz.
Israel is also intensifying its long-running strike campaign against the Iran-backed Hezbollah militia in Lebanon and expanding its ground operations in the south of the country.

The Israel Defense Forces said Wednesday that it struck two sites in Tehran that it alleged were used to produce naval cruise missiles.
The sites were used for "developing and producing long-range sea cruise missiles that enable rapid destruction of targets at sea and on land," the IDF said.
The Trump administration sent a 15-point plan to end the war to Iran that was delivered via Pakistan, two sources familiar with the plan tell ABC News.
The sources said the plan addresses Iran's ballistic missile and nuclear programs as well as maritime routes, but would not provide any other details -- including which Iranian officials were sent the proposal. It is also unclear whether Israel has signed onto the proposal.
Iran continues to insist that no negotiations are underway.
The New York Times was the first to report the proposal.
White House press secretary Karoline Leavitt said in a statement, "As President Trump and his negotiators explore this newfound possibility of diplomacy, Operation Epic Fury continues unabated to achieve the military objectives laid out by the commander in chief and the Pentagon."

Fewer than 1,500 troops from the 82nd Airborne are set to deploy to the Middle East, according to a source familiar with the matter.
The source said the mobilization will include ground forces and a headquarters element, which oversees logistics and planning. The troops are expected to leave "soon," once they have received orders being developed Tuesday, the source said.
A brigade -- about 3,000 soldiers -- of the 82nd is constantly on standby as the Immediate Response Force, tasked to be able to deploy anywhere in the world within 18 hours.
The division specializes in seizing contested territory by parachuting out of airplanes. The 82nd is light infantry -- meaning they do not come with any tanks or other large vehicles.
The 82nd Airborne Division is based out of Ft. Bragg, North Carolina, and co-located with Pope Air Force Base.
Iran has reported that a projectile hit the premises of the Bushehr Nuclear Power Plant, according to the International Atomic Energy Agency.
"According to Iran, there was no damage to the NPP itself nor injuries to staff, and the condition of the plant is normal," the IAEA Director General Rafael Mariano Grossi said in a post on X.
