A 13,000 strong UN peacekeeping force has been placed on full alert on the southern Lebanese border where the situation is said to be “tense”.
An uneasy calm has descended after the border skirmish and both sides are blaming each other for the fighting.
Lebanese Minister of State for Parliamentary Affairs Michel Faroun said: “Today we have seen the Israeli army penetrating to the Lebanese territory which has prompted the Lebanese army to answer this violation.
Israel’s foreign ministry is to file a complaint with the United Nations accusing Lebanon of violating the security council resolution that ended the recent war.
Spokesman Andy David said: “The shooting today on an Israeli IDF force that was operating in coordination with UNIFIL on the Israeli side of the border is a great violation of the UN resolution 1701.”
The four Lebanese fatalities and the death of the Israeli Lieutenant Colonel are the first casualties suffered by either side since the end of the 2006 conflict.
