At least 12 American troops were wounded after an Iranian missile strike targeted Prince Sultan Air Base in Saudi Arabia, an international news outlet has reported, citing officials.
Two of the injured personnel sustained serious wounds, while several US refueling aircraft were also damaged in the attack.
Officials stated that the strike involved both missiles and unmanned aerial vehicles.
The development comes as hostilities between the United States (US) and Iran continue, with US Central Command reporting that more than 300 American troops have been injured over four weeks of fighting.
US Secretary of State Marco Rubio said that the war could continue for “another two to four weeks,” and maintained that preventing Iran from imposing tolls on ships crossing the Strait of Hormuz would remain a challenge after the conflict.
He described such a move as “illegal” and “dangerous to the world.”
Separately, Israel carried out attacks inside Iran.
Following the escalation, oil prices crossed $100 per barrel, while US stock markets declined after President Donald Trump paused strikes on Iran’s energy sector.
In Yemen, the Houthis signalled the possibility of entering the conflict. The group said its “fingers are on the trigger for direct military intervention” if more countries join operations against Tehran or if the United States or Israel uses the Red Sea for military activity.
Iran said that it had warned three ships against passing through the Strait of Hormuz, a day after Trump extended a deadline for Tehran to reopen the route.
Iran retains control over the Strait, a route used for global oil and gas shipments, following illegal strikes by the United States and Israel.
