The designation of Larijani cites his affiliation to the Iranian Supreme Leader Ali Khamenei. Elevated to leadership of Iran's Supreme National Security Council last year, he is a veteran security and political insider of the theocracy.
Larijani, the treasury said in a statement, was "one of the first Iranian leaders to call for violence in response to the legitimate demands of the Iranian people."
"LARIJANI, Ali (Arabic: علی لاریجانی) (a.k.a. LARIJANI, Ali Ardeshir), Tehran, Iran; DOB 03 Jun 1958; POB Najaf, Iraq; nationality Iran; Additional Sanctions Information - Subject to Secondary Sanctions; Gender Male; Passport D10010646 (Iran) expires 05 Sep 2027 (individual) [IRAN-EO13876] (Linked To: KHAMENEI, Ali Husseini)," the entry on the US Treasury Department's website read.
Other sanctions targeted top officers in Iran's Islamic Revolutionary Guard Corps including provincial commanders.
The Treasury also added 13 entities to its Specially Designated Nationals (SDN) list, including Fardis Prison and companies allegedly linked to US-sanctioned Iranian trade in the United Arab Emirates, Singapore and the United Kingdom.
