The Quds Force of Iran’s Islamic Revolutionary Guard Corps has appointed a new commander to its overseas assassination unit and renamed it to Unit 600 after its personnel and structure were exposed.

Axar.az informs, citing Iran International, Esmail Qaani, commander of the IRGC’s overseas arm, recently appointed Mojtaba Hagh-Lesan to lead the unit previously known as Unit 840, the sources said.

Hagh-Lesan, 64, previously headed the unit’s intelligence department. He replaces Yazdan Mir, also known as Haj Asghar Bagheri, who was killed in a targeted Israeli strike on April 6.

The unit had been without a commander since Mir’s killing, the sources said. Hagh-Lesan’s appointment puts an existing senior member in charge of a formation linked to plots against Iranian dissidents, journalists, former US officials and Israeli targets abroad.
