Israel following Gaza model? - IDF establishes ‘Yellow line’ in southern Lebanon

Despite the entry of the ceasefire on Friday, the IDF has continued to strike Hezbollah forces deemed to be threatening its soldiers in southern Lebanon, the military announced Saturday. 

The IDF also announced the establishment of a boundary within southern Lebanon, demarcating the area to be held by Israeli soldiers during the ceasefire, which it referred to as the “Yellow Line,” as in the Gaza Ceasefire. 

“Since the ceasefire came into effect, IDF soldiers south of the Yellow Line in southern Lebanon have identified in several incidents in which terrorists violated the ceasefire understandings by approaching from north of the Yellow Line toward IDF soldiers, posing an immediate threat,” the military said in a statement Saturday afternoon. “Following their identification, and in order to remove the threat, the Israeli Air Force, together with ground forces, conducted precise strikes against the terrorists.” 

The IDF further stated that Israeli forces in the area are not prohibited by the ceasefire from acting in self-defense, or to prevent harm to Israeli civilians in northern Israel. 

“The IDF is operating in accordance with the directives of the political echelon,” the statement continued. “Accordingly, the IDF is authorized to take the necessary measures in self-defense against threats, while ensuring the security of Israeli civilians and the soldiers deployed in the area. Actions taken in self-defense and to remove immediate threats are not restricted by the ceasefire. The IDF will not allow harm to Israeli civilians and IDF soldiers and will take all necessary measures to ensure their safety.” 

The IDF says it carried out several strikes in southern Lebanon in the past day against Hezbollah operatives who "violated the ceasefire understandings."

In the Gaza Strip, the “Yellow Line” is the name given to line of demarcation between the territory held by Israel, and that under Hamas control. The IDF-controlled area represents roughly 55% of the enclave following the withdrawal of Israeli troops from active combat areas as part of the October 2025 ceasefire. 

In a similar way, the Israeli military maintains a presence in southern Lebanon, with the Yellow Line functioning as a de facto border between the Israeli forces and the communities of southern Lebanon. 

At the same time, the Yellow Line is only one of several lines of demarcation for the IDF in southern Lebanon, which it has divided into three zones: the red line, the yellow line, and the Litani River. Military officials have said that troops in the territory it holds have standing orders to eliminate any threat to their positions. 

The Yellow Line in southern Lebanon represents the area under full Israeli control. The anti-tank line, which was captured during operations in Lebanon after the start of Operation Roaring Lion, includes around 50 villages to which the Lebanese residents are not allowed to return at the present. The military is holding the line to prevent any fire on Israeli communities across the border.

During the ceasefire, the IDF will continue to operate against any Hezbollah presence, including infrastructure, inside the Yellow Line, much as it continued to destroy Hamas infrastructure inside the Gaza Yellow Line. 

The IDF has called on any Hezbollah terrorists inside the Yellow Line to surrender, or be eliminated. 

At the same time, the IDF maintains fire control over the whole area up to the Litani River. Any Hezbollah forces inside that area which approach Israeli forces will be targeted. 

Prime Minister Benjamin Netanyahu told cabinet members over the weekend that Israel must maintain freedom of action along the Yellow Line, despite the ceasefire agreement.
