Syrian and Lebanese sources report that the tunnel in which was the headquarters where Hassan Nasrallah was killed - was under the UN building in the Kharat Kharich neighborhood in Dahiya in Beirut.
Hezbollah was certain of the location of the tunnel under the building and that Israel would not attack at all in that area.
The sources state that due to the many residences of the so-called "Palestinian refugees" in the neighborhoods of Kharat Kharich and Albarajna in Dahiya - there are many buildings of the United Nations that help those "refugees".
The UN and Hezbollah is an old and long love story just like the Palestinian terrorist organizations.
In past years (during the civil war in Syria), Hezbollah took over UN humanitarian aid trucks and smuggled ammunition and explosives inside the aid areas.
