 Members of the PKK have been designated narcotics traffickers by the U.S. Department of the Treasury.The Federal Office for the Protection of the Constitution, Germany's domestic security agency, echoed this report in its 2011 Annual Report on the Protection of the Constitution, stating that despite the U.S Department of Treasury designation, there was "no evidence that the organizational structures of the PKK are directly involved in drug trafficking".On 14 October 2009, the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) targeted the senior leadership of the PKK, designating Murat Karayılan, the head of the PKK, and high-ranking members Ali Riza Altun and Zübeyir Aydar as foreign narcotics traffickers at the request of Turkey.
