According to the report, which cites seven Middle Eastern officials, including two Iranians and one American official, the explosive device was secretly brought into the Islamic Revolutionary Guard Corps (IRGC) building in Tehran approximately two months ago.

Iranian officials, who are members of the IRGC, say the precision of the strike resembled the remote-controlled machine gun used by a Mossad team to kill top Iranian nuclear scientist Mohsen Fakhrizadeh in 2020.
