The incident came hours after Israel reportedly targeted sites in Syria controlled by the Lebanese Hezbollah terrorist group.

The Iranian ally Hezbollah maintains a significant presence in southern Lebanon, despite a United Nations resolution meant to keep it out of the area.

According to Syrian and Lebanese reports, the target of the predawn strike by Israel was infrastructure set up by Hezbollah in the area of Tel al-Harra in recent months, following Syrian dictator Bashar Assad’s conquering of the area last summer.
