The Israel Defense Forces (IDF) released footage on December 20, 2025, showing troops demolishing Hamas tunnel networks on the Israeli-controlled side of the "Yellow Line" buffer zone in Khan Younis, southern Gaza. The operation involved the Kfir Infantry Brigade working alongside the elite Yahalom engineering unit, systematically destroying hundreds of militant sites, including a 2-kilometer-long tunnel and several smaller shafts.

The release coincided with the IDF's announcement that the Kfir Brigade, which had conducted months of intensive operations in the area, is being rotated out and replaced by the 188th Armored Brigade. The footage highlights precision demolitions and strategic engineering aimed at neutralizing Gaza’s extensive underground infrastructure, part of a broader post-ceasefire effort to dismantle over 1,500 kilometers of tunnels identified since October 2023.

The Kfir Brigade's rotation marks a continuation of Israel’s focus on maintaining security along the northern buffer zones, ensuring that militant capabilities are continually degraded while new units assume operational responsibility.
