Israeli authorities are investigating a civilian who has been working in the office of Prime Minister Benjamin Netanyahu and is suspected of leaking classified documents to the news media. The leaked documents supported Netanyahu's reasoning for adding tough new conditions for a cease-fire deal with Hamas over the summer. The case has caused controversy in Israel, with critics accusing Netanyahu of torpedoing a deal to return hostages and prolonging the war in Gaza for political reasons. The investigation revolves around the publication and manipulation of real and purported intelligence information in media outlets abroad. The leaks occurred after the Israeli military announced that six Israeli hostages had been found dead in a tunnel in Gaza.
