The Forum for Families, the main association representing relatives of hostages held captive in Gaza, demanded on Monday a full investigation into a document leak scandal implicating the Israeli prime minister, which may have jeopardized an agreement to free the hostages.

"The families (of hostages) demand an investigation into all individuals suspected of sabotage and compromising state security. Such actions in general, and especially during wartime, endanger the hostages, undermine their chances of return, and expose them to the risk of being killed by Hamas terrorists," the Forum stated. The association represents most of the families of the 97 hostages still held in Gaza.

On Sunday, an Israeli court announced that a former spokesman for Prime Minister Benjamin Netanyahu had been arrested for allegedly leaking confidential military documents to the press without authorization, potentially harming efforts to secure the hostages’ release. Four people, including members of Israel's security apparatus and Eliezer Feldstein, a former aide to Netanyahu, are currently in custody, according to the Rishon LeZion court. Israel's internal security agency, Shin Bet, and the military launched an investigation following the publication of foreign media reports in September based on these confidential military documents.

One report detailed a supposed plan by Yahya Sinwar, the former political leader of Hamas, to escape Gaza with the hostages to Egypt via the "Philadelphi Corridor," a buffer zone along the border. Another report was based on notes allegedly from Hamas leadership outlining a strategy by Sinwar to derail hostage release negotiations. According to the court, these reports, some of which contained false information, "compromised the security agencies' ability to achieve the goal of freeing the hostages," leading the court to impose a gag order on much of the investigation.
