The Unifill website says they mainly attacked their camera's. That suggests another possible motive, to prevent Unifill from sharing or leaking intel about IDF troop movements. > UNIFIL also came under criticism during the 2006 Lebanon War for broadcasting detailed reports of Israeli troop movements, numbers, and positions on their website which "could have exposed Israeli soldiers to grave danger", while making no such reports about Hezbollah. I find that somewhat plausible. https://en.m.wikipedia.org/wiki/United_Nations_Interim_Force_in_Lebanon
