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.

France's army chief criticized the U.S., saying the U.S. acts without informing France despite the relationship remaining "very strong" between the allies.
After the U.S. launched its war against Iran, “We acted immediately, surprised by an American ally who remains an ally but who is becoming increasingly unpredictable and doesn't even bother to inform us when they decide to launch military operations. It has an impact on our security, it has an impact on our interests," French Armed Forces Chief Fabien Mandon said Tuesday at a security and defense forum in Paris.
One person is dead and two others were injured in northern Israel after Hezbollah fired more missiles, according to Israel's emergency medical service.
At least 21 people have been killed in Israel since the start of the war.
Hezbollah said it would fight any Israeli move to occupy southern Lebanon, saying "it has always sought to occupy the south of Litani area and annex it," Hezbollah's lawyer, Hassan Fadlallah, said in a statement Tuesday.
"Now, we are facing Israeli aggression. We are in a defensive situation. The resistance fighters are battling in that area to prevent Israel from achieving this objective. This poses an existential threat to Lebanon as a state and to its geographically defined borders recognized internationally. Therefore, we have no choice but to confront this aggression and cling to the land," Fadlallah said.
