On Sunday, US military carried out air strikes in Iraq and Syria, against the Kataib Hezbollah militia group which is Iran-backed. That was in response to killing of a US civilian contractor in a rocket attack on an Iraqi military base.
US Secretary of State Mike Pompeo told reports that “we will not stand for the Islamic Republic of Iran to take actions that put American men and women in jeopardy.” Defense Secretary Mark Esper said the strikes were “successful” warned of “additional actions as necessary to ensure that we act in our own self-defense and we deter further bad behavior from militia groups or from Iran.”
