US to respond to killing of 3 troops

President Joe Biden says he has decided how to respond to the killing of three American service members in Jordan, noting that he does not want to expand war in the Middle East but demurring on the specifics of how the U.S. will proceed. U.S. officials say they are still determining which of several Iran-backed groups was responsible for the killings, the first since a wave of attacks on U.S. forces in the region since the Oct. 7 Hamas assault on Israel.
