Hassan Khalil (Arabic: حسن خليل) is the former Head of the Military Intelligence Directorate of Syria, serving from 2000 to 2005.

[1] Prior to the Syrian civil war, Khalil was a key figure in Syria’s efforts to improve relations with the United States and the West, using intelligence sharing as a significant element for cooperation.

[2] Hassan Khalil was one of several high-ranking Syrian government and military officials identified in a draft of the United Nations Mehlis Report, which was mistakenly released as a Microsoft Word document retaining all edits since its creation.

[3][4] However, the final Mehlis Report did not specifically name any Syrian government officials as responsible for the assassination.

The Syrian ambassador to Washington, Imad Mustafa, criticized the report, stating it was “full of political rumors, gossip, and hearsay.”[3] Syrian President Bashar al-Assad relied on Hassan Khalil in his capacity as head of Military Intelligence, to quel internal dissent with an "iron fist" during the Syrian uprising.
