A former Syrian general wanted for crimes against humanity, external is being bankrolled and protected by the US and Lebanese authorities, a BBC News investigation has found. Bassam al-Hassan, who oversaw Syria's chemical weapons programme and was a senior adviser to former President Bashar al-Assad, is being harboured in Lebanon following the Assad regime's collapse in 2024.

An investigation by the BBC and the US broadcaster NPR has discovered that Hassan has been allowed to remain there under an arrangement involving the FBI, and other US and Lebanese authorities. This is because of his willingness to provide information about the abduction of American journalist Austin Tice in Syria in 2012, as well as additional intelligence, we have been told.

Last month the BBC revealed Tice's abduction had been a planned operation, with Hassan in the chain of command. Officials from two different branches of Syria's new government have told the BBC they want Hassan returned to face trial, but that US authorities want him kept in Lebanon, and they say there is little Damascus can do about this.

We asked the FBI, the CIA and Lebanon's General Directorate of General Security to comment on our findings. Only the FBI responded, declining to comment and instead directing us to a past statement that said its focus remained on establishing the facts around the Tice case and securing his return.

In response to our findings, Phil Elwood, spokesperson for the Tice family said: " If what you are saying is true, the fact that our tax dollars are being used to furnish a comfortable life for someone associated with the use of chemical weapons on Syrian civilians, who claims to have had Austin Tice executed, is offensive." This is nothing less than aiding and abetting the escape of a wanted war criminal.

The Syrians deserve justice and he should be returned to stand trial." As part of a years-long investigation featured in the new BBC podcast: Where is Austin Tice?

the BBC has reviewed a detailed record of a meeting between Hassan, FBI and CIA representatives, and Lebanese security officials, where Tice's case is discussed. In it, Hassan is offered "residency", "protection" and help securing his "living needs" in return for information, primarily about Tice.

Sources with knowledge of the arrangement confirmed this was the case, and described to us how Hassan receives money from the US authorities through an intermediary, making it harder to trace. Hassan is sanctioned by the US government.
