Israel’s military said on Saturday (April 18, 2026) it had established a “Yellow Line” demarcation in southern Lebanon, similar to one separating its forces from Hamas-held areas in Gaza, adding it had hit a “terrorist cell” operating near its troops along the line.

“Over the past 24 hours, IDF forces operating south of the Yellow Line in southern Lebanon identified terrorists who violated the ceasefire understandings and approached the forces from north of the Yellow Line in a manner that posed an immediate threat,” it said, referring to such a line for the first time since a ceasefire came into effect.
