Washington CNN —The US carried out airstrikes targeting two facilities linked to Iranian-backed militias in eastern Syria on Thursday, according to a statement from Defense Secretary Lloyd Austin, following a series of drone and rocket attacks against US forces in the region. He directly accused Iran of having a role in the attacks on US forces, saying in the statement, “Iran wants to hide its hand and deny its role in these attacks against our forces. We will not let them.” Austin also promised further strikes if the attacks by Iran’s proxies continue. The US strikes follow a growing number of attacks against US forces in Iraq and Syria since October 17. It followed a similar series of drone and rocket attacks against US facilities in the region.
