The UN is calling for restraint after a border clash in which an Israeli helicopter gunship attacked a Lebanese army post with rocket fire killing four people.
Lebanese soldiers are said to have opened fire with automatic weapons. The Israeli military has confirmed the death of an Israeli officer, identifying him as a batallion commander.
The skirmish erupted as Israeli border guards attempted to remove foliage on the Lebanese side of the frontier which, they say, was obstructing their view.
The clash is the most serious exchange between the two sides since a brief war four years ago.
Milos Strugar, the UNIFIL Director of Political and Civil Affairs said: “Our acting force commander General Bonfanti has been in contact with the top leadership of the Lebanese army and with the commander of the Israeli army urging maximum restraint.”
Three Lebanese soldiers and a journalist are said to have been killed.
Hezbollah – the Iranian and Syrian-backed group which fought Israel in the 2006 war – took no part in the exchange.
