UN peacekeepers in Lebanon have been growing increasingly concerned by the activities of the Israeli army in areas adjacent to their operations.

The United Nations Interim Force in Lebanon (Unifil) was established in 1978 and since the last Israel-Hezbollah war in 2006, it is the only military force apart from the Lebanese army that should be deployed between the Israeli border and the Litani River, 30 kilometres north of the border.

Israel ordered Unifil to evacuate its bases in the areas it was operating - however, it refused.

Now, Israel has reportedly established a forward operating base within very close proximity to UN Post 6-52, which is staffed by Irish peacekeepers, raising alarm from the organisation about the possible threat to their activities.
