An Israel Defense Forces (IDF) officer was arrested amid the investigation into the leaking of intelligence documents from Prime Minister Benjamin Netanyahu’s Office, which may have affected a hostage deal, Israeli media reported on Monday. On Sunday, the Rishon Le-Zion Magistrates’ Court revealed that it had arrested Eliezer Feldstein, Netanyahu’s media adviser, as a central suspect in the case, accusing him of disclosing top-secret information with national security implications to European media. The court said that documents leaking raised “concerns of serious harm to national security and a danger to the sources of the information,” but also may have harmed “the goal of releasing the hostages” held by Hamas in the Gaza Strip.
