The Israeli military on Friday disclosed details from the interrogation of a Hezbollah operative captured in northern Lebanon about a year ago, saying the questioning yielded sensitive intelligence on what it described as one of the group’s most secret maritime projects.

In a statement posted on X by army spokesman Avichay Adraee, Israel said elite naval commandos from Unit 13 carried out a covert operation dubbed “Behind the Lines” in the Lebanese coastal town of Batroun, roughly 140 kilometers north of Israel’s border, under the direction of naval intelligence. The operation led to the capture of Imad Amhaz, identified by Israel as a senior figure in Hezbollah’s “secret maritime file” and a member of the group’s coastal missile unit, known as Unit 7900.

According to the Israeli military, Amhaz was transferred to Israel for interrogation, during which he revealed his central role in the clandestine maritime program and provided what Israel described as highly sensitive intelligence. The army said the project is among Hezbollah’s most classified undertakings and is designed to build an organized maritime infrastructure operating under civilian cover, with the aim of targeting Israeli and international interests.

Israel said Amhaz told interrogators that he had received military training in both Iran and Lebanon as part of his work with the coastal missile unit, gaining extensive maritime experience intended for conducting maritime attacks. He was also trained at a Lebanese civilian maritime institute, Marvasti, which the Israeli military cited as another example of Hezbollah’s alleged use of civilian institutions to advance its activities.

The Israeli statement said the secret maritime project was directed personally by Hezbollah’s former leader Hassan Nasrallah and by Fuad Shukr, described as the group’s most senior military commander, both of whom Israel says were killed during the war. Oversight of the file was also attributed to Ali Abdel-Hassan Nour al-Din, whom Israel identified as the official responsible for the maritime program.

According to Adraee, the intelligence obtained from Amhaz’s interrogation, combined with the killing of the project’s senior leadership, enabled the Israeli military to disrupt the maritime program at what it described as a critical stage, preventing it from becoming fully established within Hezbollah.

The Israeli military said Hezbollah continues to develop its maritime units with ideological and financial backing from Iran, accusing the group of diverting significant resources away from rebuilding Lebanon and its institutions.
