The FBI has launched an investigation into a significant leak of U.S. intelligence documents detailing Israeli plans for a potential strike on Iran. The leak has raised deep concerns within the Biden administration, with President Biden expressing his worries regarding the implications for U.S.-Israeli relations. Senior Pentagon officials, including a suspected staffer, are being scrutinized as the investigation unfolds. Reports indicate that leaked intelligence suggests Israel is refining its attack strategies, while officials assure the U.S. that any military action will target only specific military sites rather than critical infrastructure. The situation has intensified discussions around regional security, as both nations grapple with the fallout from the leak.
