An assailant has opened fire near the Supreme Court headquarters in the Iranian capital, Tehran, killing at least two judges.

Two Supreme Court judges were shot dead in Tehran on Saturday and another judge was wounded, the judiciary’s Mizan news website reported.

The victims were identified as Hojjatoleslam Ali Razini, head of Branch 39 of the Supreme Court, and Hojjatoleslam Mohammad Moqiseh, head of Branch 53 of the Supreme Court.

“This morning, an armed infiltrator in the Supreme Court acted on a pre-planned assassination of two brave judges with a long history of fighting crimes against national security, spies, and terrorism,” the statement read.

It said that according to initial findings, the person in question was not involved in any case in the Supreme Court nor was he a client of the court’s branches.

“Right after the terrorist act, an attempt was made to arrest the gunman, who then quickly committed suicide,” it added.

The Judiciary further said an investigation has been launched to identify and arrest those behind this terrorist act.
