Two U.S. soldiers and an American civilian interpreter were killed during an attack Saturday near the city of Palmyra, Syria, according to the Pentagon. Three additional U.S. soldiers were wounded in the assault, the Pentagon added. President Trump in a social-media post called it “an ISIS attack against the U.S., and Syria, in a very dangerous part of Syria.” He warned “there will be very serious retaliation,” adding that Syrian President Ahmed al-Sharaa, the former al Qaeda and Islamist rebel commander, “is extremely angry and disturbed by this attack.”
