OFAC has designated Muhammad Al-Mansur, an Iraqi national resident in Turkey, as a Specially Designated Global Terrorist for acting as a finance emir for ISIL. He is said to have been involved with al-Qaida in Iraq since 2009, acting as a fundraiser, and to have laundered and transferred substantial sums of money on behalf of ISIL since around 2014. Since 2016, he is said to have been responsible for selling crude oil that ISIL extracted from oil fields in Iraq and Syria.
In the US Treasury’s press release, OFAC Director John Smith said that the Treasury “continues to work in close collaboration with the Government of Iraq to dismantle ISIS financial networks”. Details of the listing are here.
