Two U.S. troops killed in Iranian missile attack on Jordan

Two U.S. service members were killed and more wounded in an Iranian ballistic missile attack on an airbase in Jordan on Saturday, military officials said. The big picture: This is the first time U.S. troops have been killed since the fighting resumed two weeks ago. The incident raises the number of U.S. service members killed in the war to 16. Driving the news: On Saturday at least two Iranian ballistic missiles hit the Muwaffaq Salti Air Base in Jordan, which hosts U.S. troops and fighter jets. Videos circulating on social media showed the impact of the two missiles and heavy smoke in the area right after. CENTCOM confirmed that two service members were killed and another was missing; four more were evacuated to hospitals for treatment. The latest: On Saturday around 6 p.m. ET the U.S. military conducted another round of strikes against Iranian targets. "The strikes are designed to further degrade Iran's ability to threaten commercial shipping in the Strait of Hormuz and swiftly punish Islamic Revolutionary Guard Corps forces who launched attacks against American service members in Jordan last night," CENTCOM said in a statement. Behind the scenes: Two U.S. officials said there have been four different Iranian missile attacks that hit U.S. forces on bases in Jordan over the the last week. Dozens of U.S. service members were wounded in the attacks and several helicopters were destroyed, one U.S. official said. The U.S. official expressed concern that the four incidents signal that Iran has managed to exploit vulnerabilities in the U.S. defenses in Jordan. What they're saying: President TrumptoldNewsNation that the death of service members was "a very sad thing." Asked about Iranian claims that they would no longer follow the Memorandum of Understanding the two countries signed in June, Trump reportedly said: "I couldn't care less."
