Video: UN observes heavy Israeli troop movement near southern Lebanon UN spokesperson Stephane Dujarric said peacekeepers in southern Lebanon continue to observe extensive Israeli military activity, including “high-density armoured movements, large-scale engineering and demolition works and sustained logistical traffic” in areas near the border. Dujarric said the UN peacekeeping mission, Unifil, also recorded intensive air activity involving fighter aircraft and drones. Of 531 trajectories monitored on Thursday, 526 originated from Israeli positions south of the Blue Line and within Unifil's area of operations, while five were believed to have been launched by Hezbollah, with one crossing the UN-demarcated frontier, he said.
