The Pentagon says U.S. warplanes have carried out two more airstrikes in Syria in response to dozens of drone and missile attacks on bases housing Pentagon forces in Syria and Iraq that have injured at least 56 military personnel. Reuters reports one of the U.S. strikes targeted a camp run by pro-Iranian armed groups in Deir ez-Zor province; another struck near a bridge close to the city of Mayadeen, close to the Iraqi border. It’s at least the third round of U.S. airstrikes in Syria in just over two weeks.
