Photos show US pilot being rescued after apparently ejecting over Kuwait - as smoke seen rising near the US embassy

The first American service members to die in the U.S.-Israeli war with Iran were killed in an apparent Iranian drone attack on a makeshift office space in Kuwait, sources told CBS News.

The U.S. State Department closed embassies in Kuwait and Saudi Arabia on Tuesday and is urging Americans to evacuate from 14 Middle Eastern countries as the war with Iran escalates.

The first US service members to die in the conflict between the US and Iran were killed by a direct Iranian strike on a makeshift operations center at a civilian port in Kuwait on Sunday morning

Separately, a drone attack hit the U.S. Embassy compound in the Persian Gulf state, as Iran continues to target American assets across the Middle East.

The toll from a strike on a girls' elementary school in Minab, Iran, has risen to 85 students dead and 60 others injured, according to Iran's semiofficial Tasnim News Agency, which cited the local governor. Iran claims the school was struck during the U.S.-Israeli military operation on Saturday.

Trump said the strikes were intended to eliminate "imminent threats" from Iran and prevent the country from obtaining a nuclear weapon.
