In recent months, since Operation Wall Guard, we have been increasingly exposed to the concept of "Palestinian organizations in Lebanon," the same organizations that, according to the defense establishment, are responsible for a number of rocket fire incidents on the northern border. 

Meet the Lebanese branch of Hamas:

Hamas, the Lebanese branch, operates mainly in southern Lebanon, but not only that, the branch operates as an organization with a military arm with several units, it produces weapons and manages an economic network that is used to buy weapons and equipment.
The organization has a production line that is responsible for the production of rockets and drones, as part of the system's activities it purchased warheads and began producing fuel to develop its capabilities and produce rockets independently and independently.

For years, the formation built rocket workshops in factories it set up in Lebanon, without Hezbollah's knowledge.
All the activities of the formation are carried out under a cloak of secrecy and in civilian disguise, in secret from the State of Lebanon and the leadership of Hezbollah.

The organization also has a construction department that is responsible for developing covert capabilities for Hamas anti-personnel missiles around the world. The leadership of the department is located mostly in Turkey.

The head of the unit is Majed Khachar  , known as Abu Fadi, 55, who lives in Istanbul.
His deputy is allowed Abrahaim and opinion Salem , a mechanical engineer by training, in charge of Hamas's R & D capabilities, including drones and weapons projects autonomous diving for vulnerable vessels, type of weapon it  was almost completely destroyed in Gaza during Operation gatekeeper.
Despite its impressive repertoire, Salem and his campaign are unable to meet the goals set for them by Hamas. He mostly failed when Salem's activists were exposed and their activities stopped.
