Smoke was seen rising in the vicinity of the U.S. Embassy compound in Kuwait after Iran and Iranian-backed militias targeted Israel and Arab states with missile attacks.

This comes after a joint U.S.-Israeli strikes against Iran over the weekend that killed the Islamic Republic’s Supreme Leader Ali Khamenei.

The U.S. and Israel struck targets in Iran as the war expanded on Monday.

Fire and smoke rose from the vicinity of the embassy compound in Kuwait City and an alarm was heard after the Iranian attack, which came shortly after the U.S. issued a warning to Americans in the area to take cover and for others to stay away.

There were no immediate reports on damage or casualties.

This came amid reports of several U.S. warplanes crashing in Kuwait, according to the country's defense ministry. All the pilots were safely bailed out. The ministry did not say what caused the crashes, but they happened during an intense period of Iranian fire toward Kuwait.

The pilots had been transported to a hospital in stable condition.
