DUBAI, United Arab Emirates — Iran’s supreme leader warned Sunday that any attack by the United States would spark a “regional war” in the Mideast, further escalating tensions as President Donald Trump has threatened to militarily strike the Islamic Republic.
The comments from the 86-year-old Ayatollah Ali Khamenei are the most-direct threat he’s made so far as the aircraft carrier USS Abraham Lincoln and associated American warships are in the Arabian Sea, sent by Trump there after Tehran’s bloody crackdown on nationwide protests.
It remains unclear whether Trump will use force. He’s repeatedly said Iran wants to negotiate and has brought up Tehran’s nuclear program as another issue he wants to see resolved.
But Khamenei also referred to the nationwide protests as “a coup,” hardening the government’s position as tens of thousands of people reportedly have been detained since the start of the demonstrations. Seditious charges in Iran can carry the death penalty, which again renews concerns about Tehran carrying out mass executions for those arrested — a red line for Trump.
Iran had also planned a live-fire military drill for Sunday and Monday in the strategic Strait of Hormuz, the narrow mouth of the Persian Gulf through which a fifth of all oil traded passes. The U.S. military’s Central Command had warned against threatening American warships or aircraft during the drill or disrupting commercial traffic.
Khamenei warns US
Iranian state television reported Khamenei’s comments online before airing any footage of his remarks.
“The Americans should know that if they start a war, this time it will be a regional war,” Khamenei was quoted as saying.

It added that Khamenei said: “We are not the instigators and we do not seek to attack any country. But the Iranian nation will deliver a firm blow to anyone who attacks or harasses it.”
Khamenei also hardened his position on the demonstrations after earlier acknowledging some people had legitimate economic grievances that sparked their protests. The demonstrations began Dec. 28, initially over the collapse of Iran’s rial currency. It soon grew into a direct challenge to Khamenei’s rule.
“The recent sedition was similar to a coup. Of course, the coup was suppressed,” he said. “Their goal was to destroy sensitive and effective centers involved in running the country, and for this reason they attacked the police, government centers, (Revolutionary Guard) facilities, banks and mosques — and burned copies of the Quran. They targeted centers that run the country.”
Parliament speaker says EU militaries considered terrorist groups.
The speaker of Iran’s parliament, meanwhile, said that the Islamic Republic now considers all European Union militaries to be terrorist groups, lashing out after the bloc declared the country’s paramilitary Revolutionary Guard a terror group over its bloody crackdown on nationwide protests.
Mohammad Bagher Qalibaf, a former Guard commander, announced the terror designation, which will likely be mostly symbolic. Iran has used a 2019 law to reciprocally declare other nations’ militaries terror groups following the United States declaration of the Guard a terror group that year.
Qalibaf made the announcement as he and others in parliament wore Guard uniforms in support of the force. The Guard, which also controls Iran’s ballistic missile arsenal and has vast economic interests in Iran, answers only to Iran’s 86-year-old Khamenei.
“By seeking to strike at the (Guard), which itself has been the greatest barrier to the spread of terrorism to Europe, Europeans have in fact shot themselves in the foot and, once again, through blind obedience to the Americans, decided against the interests of their own people,” Qalibaf said.
Lawmakers at the session later chanted: “Death to America!” and “Death to Israel!” at the session.
Trump says Iran is ‘seriously talking’ to US
Trump has laid out two red lines for military action: the killing of peaceful protesters or the possible mass execution of those detained in a major crackdown over the demonstrations. He’s increasingly begun discussing Iran’s nuclear program as well, which the U.S. negotiated over with Tehran in multiple sessions before Israel launched a 12-day war with Iran back in June.
The U.S. bombed three Iranian nuclear sites during the war. Activity at two of the sites suggests Iran may be trying to obscure the view of satellites as it tries to salvage what remains there.
Trump on Saturday night declined to say whether he’d made a decision on what he wanted to do regarding Iran.
Speaking to reporters as he flew to Florida, Trump sidestepped a question about whether Tehran would be emboldened if the U.S. backed away from launching strikes on Iran, saying, “Some people think that. Some people don’t.”
Trump said Iran should negotiate a “satisfactory” deal to prevent the Middle Eastern country from getting any nuclear weapons, but said, “I don’t know that they will. But they are talking to us. Seriously talking to us.”
Ali Larijani, a top security official in Iran, wrote on X late Saturday that “structural arrangements for negotiations are progressing.” However, there is no public sign of any direct talks with the United States, something Khamenei has repeatedly ruled out.
