An Israeli airstrike in central Iran’s Mahallat city has killed the chief engineering officer of the Islamic Revolutionary Guard Corps’ (IRGC) Quds Force, according to the Israeli military. The Israel Defense Forces (IDF) stated that the strike took place on Tuesday and identified the victim as Mahdi Wafai, who was described as the head engineer of the Quds Force’s Lebanon Corps.

In its statement, the IDF said Wafai had been involved for two decades in advancing secret projects in Lebanon and Syria, including building infrastructure and managing arsenals for Hezbollah. The military further claimed that he led efforts to construct underground facilities for Hezbollah and the Syrian government of Bashar al-Assad, and oversaw dozens of underground projects used to store advanced weapons in Lebanon.

Iranian authorities have not issued any immediate comment regarding the reported strike or the death of Wafai, according to the source.
