Israel has established a military zone inside southern Lebanon that critics say violates the terms of the ceasefire agreement that halted fighting between Israeli forces and Hezbollah, according to a report by Al Jazeera.

The zone, which Israeli officials have referred to as the "Yellow Line," involves Israeli military presence on Lebanese sovereign territory beyond the internationally recognized border. The move has raised fears among observers and Lebanese officials that Israel is replicating a strategy it has employed in Gaza, where a similar buffer zone has been carved out along the territory's edges.

What is the Yellow Line?

The Yellow Line refers to a designated military perimeter that Israeli forces have established inside Lebanese territory. The creation of such a zone raises questions about compliance with the ceasefire deal brokered in late 2024, which was intended to end hostilities between Israel and Hezbollah and required Israeli forces to withdraw from Lebanese soil.

The ceasefire agreement had set a deadline for Israeli troop withdrawal, with the Lebanese army expected to deploy to the south as Israeli forces pulled back. The continued Israeli military presence inside Lebanese territory has complicated that process.

Parallels to Gaza

Al Jazeera's reporting draws a direct comparison between the Yellow Line in Lebanon and Israeli buffer zone practices in Gaza, where Israeli forces have maintained positions inside the territory's perimeter even during periods of reduced fighting. Critics argue that the establishment of such zones effectively annexes portions of a neighboring territory without a formal legal framework.

Lebanese officials and international observers have expressed concern that the buffer zone strategy, if sustained, could permanently alter the territorial and security landscape of southern Lebanon, a region that has already suffered significant destruction from the conflict.

International response

The United Nations Interim Force in Lebanon, known as UNIFIL, has been monitoring the situation along the border. The continued presence of Israeli forces in southern Lebanon has complicated the deployment of the Lebanese Armed Forces, which was a central component of the ceasefire arrangement.

The United States and France, both key brokers of the ceasefire agreement, have not publicly commented on the Yellow Line designation, according to the Al Jazeera report. The Lebanese government has called for full Israeli withdrawal in line with the agreed terms.

The situation remains unresolved, with the Yellow Line representing one of several unaddressed elements of a ceasefire that both sides have accused the other of violating since the agreement took effect.
