President Trump is defending his decision to start the war with Iran, saying in the Oval Office on Tuesday that there would have been a nuclear war without intervention, and that Iran "would have taken out many countries." Israel sent troops into Lebanon as the war expanded, and some of Iran's Gulf neighbors warned that Iran's retaliatory fire could draw them into the spreading conflict.

The U.S. consulate in Dubai was struck by a drone. Americans are being advised to leave 14 countries in the region because of "serious safety risks," and the U.S. embassies in Beirut, Kuwait, and Saudi Arabia are closed because of the conflict. Six U.S. troops have been killed. The Iranian Red Crescent reported that at least 787 people have been killed in Iran, but reports inside the country suggest the toll is likely in the thousands. The Pentagon released the names of four U.S. service members killed in an Iranian counterattack in Kuwait. Two other Americans have not yet been identified.
