A senior Syrian official denied asylum in France due to concerns of possible involvement in war crimes was spirited out of the country with help from the Israeli secret service Mossad to Austria, where he was helped to start a new life, a top judicial source has told The Telegraph. Brigadier General Khaled al-Halabi, who was chief of Syrian intelligence in Raqqa from 2009 until 2013, is also the target of a legal complaint for alleged war crimes and crimes against humanity, a Telegraph investigation can reveal. During his time in charge of the Raqqa facility, prisoners were allegedly murdered, tortured and sexually assaulted, according to the complaint filed in a Western country and which has been sent to the Paris prosecutor. Mr Halabi vehemently denies any wrongdoing. In spite of human rights concerns about his unit, France’s spy agency, Direction Générale de la Ssécurité Extérieure, (DGSE), helped the general secretly leave Syria and travel to France in 2014 at a time when Syria’s war against rebel forces was in the balance, it is alleged. He was, however, then denied asylum in France due to concerns that his senior position in the Syrian regime meant he could have been involved in criminal acts, The Telegraph has learned. That prompted the French War Crimes Unit to launch a preliminary investigation in 2017. In spite of this, he was then mysteriously exfiltrated from France by Israeli intelligence agents to Austria, where he was successfully granted asylum, according to the judicial source and French and Austrian media. The agencies involved allegedly believed Mr Halabi could play an important role in the future of Syria. “It's clear he is a big fish,” said one senior French judicial source. “We wanted to quiz him about all the testimonies we have gathered. It is very frustrating as he was a top target."
