The U.S. launched strikes on Iran after new Iranian attacks on vessels.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Delegations from the U.S. and Iran entered negotiations last month aimed at a war-ending deal based on a memorandum of understanding signed by both countries.
The U.S. and Iran nonetheless exchanged limited strikes in late June despite the signing of the memorandum and amid the continuation of peace talks.
Eight members of the Iranian army were killed in U.S. attacks on southern parts of Iran early on Wednesday, Iranian state media reported.
The victims belonged to the air force and navy and died due to strikes in Bandar Abbas and Bushehr, it added.
Iran's Foreign Minister Abbas Araghchi said Iran does not respond to "vulgarity with vulgarity," but rather "with action: fearlessly and with great valor," in a post on X Wednesday.
While Araghchi did not directly mention President Donald Trump's comments to reporters, the post came after his remarks about Iranian leaders, describing them as "scum" on Tuesday evening and again on Wednesday.
Iran's foreign ministry spokesman Esmaeil Baqaei also said the U.S. has challenged a clause in the Memorandum of Understanding between the two countries that "emphasizes the Islamic Republic of Iran's responsibility in determining arrangements for the safe passage of ships through the Strait of Hormuz," in another post on X.
Baqaei added that the MoU "was not established on the basis of trust, but rather on the clear mechanism of commitment for commitment," and that Iran will "steadfastly pursue the protection of its national interests and the exercise of its sovereignty."
President Donald Trump was pressed on his plans to leave Turkey in the old Air Force One after he repeatedly emphasized on Wednesday that Iran desired to assassinate him.
Asked if security concerns caused the change in flight plans, Trump said, "I'm No. 1 on the kill list for Iran."
"So, I don’t know, I can’t really tell you that. But I don't really care because I'm doing my job and I'm doing it, I hope, better than anybody has ever done it," Trump added.
The president flew to Turkey in the Qatari-gifted “bridge” Air Force One, which entered into service last month.
Again pressed on why he was not flying out on the new plane, Trump re-stated that it was going to Europe for American servicemembers to tour.
President Donald Trump told reporters that he doesn't think the war with Iran will begin again, saying that "anything that happens will be over very quickly."
"I don't think it's going to start again. I think it's going to go very quickly. They hit a couple of ships, and so we hit them much harder. When they hit, we hit 10 times harder," Trump said at a NATO press conference held in Turkey.
"I think anything that happens is going to be over very quickly, and will only make it safer, including for oil. Oil is going to be very free, very free, very easy, and it's going to happen very fast," Trump said.
Trump also said there is a "gusher of oil" now, reemphasizing that anything that happens will be over quickly.
"We're not looking for long term," Trump said.
