According to Arab sources, Israel attacked an important compound of Hezbollah's air arm that included a large number of destroyed UAVs.

But no less important than that and maybe more. The Lebanese "A-Nahar" newspaper, which is considered reliable, cites sources according to which the bureau of the Lebanese Ministry of Industry in the Baalbak area also operated in this complex. 

In other words, there is no real separation today between Hezbollah and the government or state of Lebanon. The Lebanese government operates in the same compounds that Hezbollah uses for its military needs.

Note: The video shows the dimensions of the destruction of the night attack in Baalbek.
