Iran's Supreme Leader Warns Any U.S. Attack Would Spark 'Regional War'

Ayatollah Ali Khamenei spoke to a crowd at his compound in Tehran as Iran marked the start of a dayslong commemoration of the country's 1979 Islamic Revolution.

DUBAI, United Arab Emirates (AP) — 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 over its crackdown on recent nationwide protests.

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. Sedition 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.
