Iran-backed Hezbollah is now operating under the direct control of officers from Tehran’s Islamic Revolutionary Guard Corps, according to sources cited by Saudi outlet Al-Arabiya, as Israel carried out airstrikes in Lebanon and regional tensions continue to rise.

The sources told Al-Arabiya that IRGC officers, some of whom recently arrived in Lebanon from Iran, have assumed responsibility for restructuring Hezbollah’s military capabilities. They said the officers have been briefing fighters across the country as Iran prepares for a potential war with the United States and Israel.

According to the report, IRGC personnel were meeting with members of Hezbollah’s missile unit at a location in Lebanon’s Beqaa Valley that was struck by Israel overnight. The strikes were part of a wave of Israeli air attacks that wounded at least 50 people and killed 12, including a senior Hezbollah officer, targeting what the Israel Defense Forces said were Hamas and Hezbollah command centers in Lebanon.
