The Israeli military has determined that the brother of the man who drove his truck through a Michigan synagogue last week was a commander for Hezbollah, the terrorist group and Iranian proxy force based in Lebanon.

Last Thursday, 41-year-old Ayman Mohamad Ghazali, a naturalized U.S. citizen from Lebanon, rammed his vehicle into the Temple Israel synagogue in Michigan, driving through the halls before exchanging fire with security officers. His vehicle, loaded with explosives, caught fire and was jammed in the hallway, leading to Ghazali killing himself. One security guard was injured in the attack, but all children and staff at the temple’s preschool had been safely evacuated.
