In an effort to retaliate for the Iran-backed Iraqi militia attack that killed a U.S. civilian contractor, the U.S. has conducted air strikes in Syria and Iraq. According to the defense department, on Sunday weapons caches and command and control centres at five sites associated with Kataib Hezbollah were hit. 25 fighters were killed; 51 injured. Mike Pompeo, U.S. Secretary of State, previously stated that actions taken by Iran that put Americans and allies in danger would not be stood for. To degrade their ability to conduct attacks against U.S.-led coalition forces, precision defensive strikes have been conducted against three Kataib Hezbollah facilities and two in Syria. According to Mark Esper, U.S. Defense Secretary, the strikes were successful. Other options to discourage further attacks are also being discussed with President Trump.
