Golani Brigade fighters have been engaged during the past two weeks in targeted operations to locate and investigate a significant Hamas underground infrastructure near the European Hospital in Khan Younis, where the body of Mohammed Sinwar was found. This was reported by the IDF spokesperson, who added that after completing the investigation of the tunnel, it was neutralized in a complex logistical and engineering operation. According to the IDF spokesperson, dozens of trucks and concrete mixers pumped about 250 cubic meters of concrete into the tunnel and sealed it.
