On 30 September, OFAC released new FAQ 932. This asks: do US sanctions prohibit US persons from visiting, or making donations to, the Imam Reza Holy Shrine in Mashhad, Iran? It notes that The Holy Shrine Organization is also considered blocked under Executive Order 13876 pursuant to OFAC 50% Rule to the extent it is 50% or more owned by Astan Quds Razavi (AQR), and that US persons are advised to act with caution when considering transactions or activities involving AQR or the Holy Shrine Organization.
