Hassan was appointed head of the Syrian Air Force Intelligence Directorate in 2009.[2]
Sanctions
Hassan was sanctioned by the European Union on 9 May 2011.[3][4][5] He was added to the European Union's sanction list on the grounds that he "involved in violence against the civilian population" during the Syrian civil war.[6] On 29 June 2011, the United States also sanctioned him due to his involvement in human rights abuses in Syria.[7]
Hassan gave an interview for The Independent in November 2016, proving the claims of his death false. He stated that the tactics used in the 1982 Hama revolt would have ended the Syrian Civil War much faster.[10]
In November 2018, French prosecutors issued international arrest warrants for three senior Syrian intelligence and government officials: Ali Mamlouk, Abdel Salam Mahmoud and Jamil Hassan. The warrants bring charges including collusion in torture, forced disappearances, crimes against humanity and war crimes.[12] Four days of hearings at the Paris Cour d'assises started on 21 May 2024, accusing the three men of involvement in the disappearance, torture and killing of two French citizens between 2013 and 2017.[13] Hassan was convicted and sentenced to life imprisonment in absentia on May 25.[14][15]
