The U.S. military said Monday that three F-15E fighter jets were “mistakenly shot down” by Kuwaiti air defenses during operations responding to Iranian attacks in the region. All six crew members ejected safely and have been recovered in stable condition.

The incident occurred as Iran and Iranian-backed militias launched missiles at Israel and Gulf states, reportedly striking the U.S. Embassy compound in Kuwait. Israel and the U.S. conducted retaliatory strikes on Iran, targeting missile sites, naval assets, and nuclear facilities.

The Iranian Red Crescent reported at least 555 deaths in Iran, while Israeli authorities confirmed 11 fatalities and Lebanon’s health ministry reported 31 deaths following airstrikes. In Kuwait, several U.S. warplanes also crashed, though pilots were unharmed.

The conflict has spread to regional energy infrastructure. Saudi Arabia’s Ras Tanura oil refinery was targeted by drones, prompting a temporary shutdown, while Oman reported a drone boat attack on a tanker, killing one crew member. Debris from intercepted drones caused injuries at Kuwait’s Ahmadi refinery. Analysts warn these attacks on Gulf oil facilities mark a significant escalation and pose broader economic risks.

Hezbollah fired missiles into Israel from Lebanon, triggering Israeli airstrikes that killed at least 31 people and wounded 149, mostly in the south. In Iraq, a pro-Iranian militia targeted U.S. troops with drones in Baghdad and Irbil, and Cyprus reported drone damage at a British airbase.

The U.S. has vowed to continue combat operations until objectives are achieved. President Donald Trump promised to “avenge” the deaths of three American troops in Kuwait while warning of further casualties.

The World Health Organization urged all parties to protect civilians and medical facilities amid the escalating conflict, as missiles and drones continued to strike cities across Iran, Israel, and the Gulf.
