There is no proof that Lebanese Hezbollah was responsible for the Magdal Shams incident you are referring to, and all of the facts suggest that it was an accident. It happened during what was virtually a firefight.

The Magdal Shams is a village in the Golan heights, which is a Syrian area that is illegally occupied by Israel. At the very least, it is a huge leap of faith to assume that the families of the victims condemn Hezbollah or Israel or who they think is responsible.

Whatever your beliefs are, I suggest not jumping to conclusions so quickly, especially on such a complicated topic
