The Israeli Defense Forces (IDF) disclosed on December 19, 2025, between 8:15 AM and 10:16 AM UTC, details of the Sheitat 13 operation conducted last year in the town of Batron, northern Lebanon, 140 km from the Israeli border, where Hezbollah captain Imad Amhaz from the secret Coastal Missile Unit 7900 was captured, according to the IDF spokesman in Arabic. Amhaz, who underwent military training in Iran and Lebanon and at the Lebanese Civil Naval Institute Maresti, admitted during interrogation to a central role in Hezbollah's "Secret Naval File," one of its most sensitive projects directly managed by Hassan Nasrallah and Fuad Shukr, the latter eliminated early in the war, as stated by the IDF. The IDF also revealed Ali Abdul Hassan Nur al-Din as responsible for the secret naval file. Separately, during the same period, IDF forces visited Tirharfa, a Shia village in southern Lebanon on the second line from the border, as part of the ground maneuver in the "Northern Half," according to an X post by Ben Tzion Macales.
