US strikes Iran for 10th night, Trump threatens escalation as State Department warns citizens globally

Overnight strikes

American forces struck Iranian military command centers, missile bases, and air defense systems in a five-hour operation ending at 21:00 Eastern time on Monday (03:00 Tuesday in Poland), US Central Command (CENTCOM) said. The operation marked the tenth consecutive night of American strikes against targets in Iran.

Iran's Islamic Revolutionary Guard Corps said two tankers caught fire after explosions as they tried to pass through the Strait of Hormuz. Tehran said the strait would remain closed as long as US actions in the region continued. CENTCOM countered that commercial shipping traffic was flowing, stating that its forces had helped secure transit for about 900 merchant vessels and 450 million barrels of oil since the beginning of May.

US forces remain ready and prepared to hold Iran accountable for unwarranted aggression against civilian mariners seeking free and open passage through the strait.

US citizens warned worldwide

The State Department issued a worldwide alert on Monday evening, citing heightened tensions in the Middle East and the potential for unforeseen escalation. Americans in the region were advised to exercise caution, remain vigilant, and prepare for possible flight cancellations, periodic airspace closures, and travel disruptions.

The warning noted that US diplomatic facilities, including those outside the Middle East, have been targeted. "Iran and Iran-backed groups could attack other American interests abroad or facilities tied to the United States and Americans around the world," the department said.

Trump warns Iran over troop deaths

President Donald Trump threatened Monday that Iran would face "multiply worse consequences" each time it kills an American soldier. At least three US military personnel died in the region over the weekend.

Two soldiers were killed, and one was listed as missing, after an Iranian attack on an air base in Jordan on Friday; human remains were found at the site on Sunday and identification is underway. Another soldier died in northern Iraq on Saturday during a controlled detonation of unexploded ordnance from a downed Iranian kamikaze drone. The deaths bring the US military toll to 17 killed and roughly 430 wounded since 28 February, when Israel and the US launched operations against Iran, Reuters reported.

A US administration official told Axios that Trump is focused on making Iran "face consequences for violating the preliminary agreement with the US" and for further "acts of terrorism" in the Strait of Hormuz. The official said strikes would continue until the president decides otherwise but confirmed that talks between Washington and Tehran are ongoing.

Houthi front opens

Yemen's Houthi rebels announced a naval blockade of Saudi Arabia in a televised address, Reuters reported. The move opens a new front in the wider regional conflict that has seen daily exchanges since mid-June, when a ceasefire agreed earlier between the US and Iran collapsed amid divergent interpretations of provisions governing control of the Strait of Hormuz.
