The Israeli military has killed Abu al-Qassem Babayian, who had recently been appointed the head of Iran's Supreme Leader's military office, according to a statement released by the Israeli Defense Ministry on Sunday.

The appointment comes just days after his predecessor was killed in the exchange of fire triggered by U.S.-Israeli strikes on Iran starting on Feb. 28, according to the statement.

Israeli Defense Minister Israel Katz was briefed on Babayian's killing during a situation assessment with army chief Eyal Zamir and other senior officers.

On Feb. 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's Supreme Leader Ali Khamenei, along with several senior military commanders and civilians. Iran later launched multiple waves of missile and drone strikes targeting Israeli and U.S. bases in the Middle East.

On Sunday, Iran's Assembly of Experts has finalized a decision on its new supreme leader, the semi-official Mehr news agency reported.
