In recent weeks, the IDF has shot down four UAVs that have crossed the Lebanese territory in the direction of Israel. These specific events reflect the tension with Hezbollah. This, following the placement of a shark rig located in Israel's economic waters, near the border. 

Israel is now threatening Hezbollah and warning of other similar actions - and even raising closed discussions to examine the possibility of moving the shark rig out of place.
