Iran's supreme leader threatens Israel and US with 'a crushing response' over Israeli attack

Iran's supreme leader on Saturday threatened Israel and the U.S. with "a crushing response" over attacks on Iran and its allies.

Ayatollah Ali Khamenei spoke as Iranian officials are increasingly threatening to launch yet another strike against Israel after its October 26 on the Islamic Republic that targeted military bases and other locations and killed at least five people.

Any further attacks from either side could engulf the wider Middle East, already teetering over the Israel-Hamas war in the Gaza Strip and Israel's ground invasion of Lebanon, into a wider regional conflict just head of the U.S. presidential election this Tuesday.

"The enemies, whether the Zionist regime or the United States of America, will definitely receive a crushing response to what they are doing to Iran and the Iranian nation and to the resistance front," Khamenei said in video released by Iranian state media.

The supreme leader did not elaborate on the timing of the threatened attack, nor the scope. The U.S. military operates throughout the Middle East, with some troops now manning a Terminal High Altitude Area Defense, or THAAD, battery in Israel.

The 85-year-old Khamenei had struck a more cautious approach in earlier remarks, saying officials would weigh Iran's response and that Israel's attack "should not be exaggerated nor downplayed."

Khamenei on Saturday met with university students to mark Students Day, which commemorates a November 4, 1978, incident in which Iranian soldiers opened fire on students protesting the rule of the shah at Tehran University.

The shooting killed and wounded several students and further escalated the tensions consuming Iran at the time that eventually led to the shah fleeing the country and the 1979 Islamic Revolution.

The crowd offered a raucous welcome to Khamenei, chanting: "The blood in our veins is a gift to our leader!" Some also made a hand gesture given by the slain Hezbollah leader Hassan Nasrallah in 2020 in a speech in which he threatened that American troops would "return in coffins."

Iran will mark the 45th anniversary of the U.S. Embassy hostage crisis this Sunday, following the Persian calendar.

The November 4, 1979, storming of the embassy by Islamist students led to the 444-day crisis, which cemented the decades-long enmity between Tehran and Washington that persists today.
