The Supreme Leader of Iran, Ali Khamenei, on Friday appointed new military commanders following the deaths of key security officials in Israeli airstrikes on Tehran, local media reported.

The appointments comes after Israel launched a wave of airstrikes early Friday targeting Tehran and other cities in Iran.

The strikes killed Chief of Staff of the Armed Forces Mohammad Bagheri, Islamic Revolution Guard Corps (IRGC) Commander Hossein Salami, and Gholam-Ali Rashid, head of the Khatam al-Anbiya Central Headquarters, the report said.

Khamenei named Abdolrahim Mousavi as the new chief of staff of the armed forces, Mohammad Pakpour as the IRGC’s new commander, and Ali Shadmani to lead the Khatam al-Anbiya Central Headquarters.

Before their appointments, Mousavi headed the regular army, Pakpour commanded the IRGC’s Ground Force, and Shadmani served as deputy coordinator at Khatam al-Anbiya.

In addition to the top military leaders, the Israeli strikes also killed six Iranian nuclear scientists, including Mohammad-Mehdi Tehranchi and Fereydoun Abbasi, as well as an unspecified number of civilians, the report added.

In a statement, Khamenei condemned the attacks, warning that Israel would face “severe punishment” for what he called a crime against Iran.
