IDF Destroys Hamas’ Largest Tunnel Discovered Yet

The IDF announced Wednesday the destruction and sealing of Hamas’s largest tunnel discovered yet, initially disclosed by the military in December.

According to recent statements from the IDF, efforts were concentrated over the past weeks on conducting a thorough investigation of the tunnel followed by its demolition. Combat engineers were responsible for detonating parts of the tunnel, while concrete was used to fill the remaining underground passages.

The tunnel, spanning approximately 4 kilometers (2.5 miles) and reaching depths of around 50 meters (165 feet) in certain sections, was evidently designed with enough width to accommodate vehicle passage. Although not extending into Israeli territory, officials characterized it as intended for offensive operations rather than for defensive purposes or civilian transportation.

One of the tunnel entrances was located just 400 meters (a quarter mile) from the Erez crossing, previously used by Palestinian civilians for access to work opportunities and medical care in Israel until Hamas’s aggression on Oct. 7 disrupted this movement.

The IDF attributed the construction of the tunnel to Muhammad Sinwar, commander of Hamas’s southern brigade and brother of Hamas leader Yahya Sinwar. Footage released by the IDF in December depicted Muhammad Sinwar driving through the tunnel in a car, obtained from sources within the Gaza Strip.
