The Iranian military's new head of emergency command was killed in an Israeli Air Force strike only four days after his predecessor was killed in the initial hours of Israel's strikes targeting Iran's nuclear program.

Iran has been forced to replace several military leaders, including the head of the army and the IRGC.

The IDF on Tuesday morning said it killed Iran's "most senior military commander, and the closest figure to Iranian Supreme Leader Ali Khamenei" late on Monday night.
