DUBAI: Syrian authorities have asked Lebanese security forces to hand over more than 200 senior officers who fled to Lebanon after the fall of Bashar Assad, following a Reuters investigation that showed how the neighboring country was a hub for insurgent plotting. On Dec. 18, a top Syrian security official, Brig. Abdul Rahman Al-Dabbagh, met with his Lebanese counterparts in Beirut to discuss the exiled Assad-era officers, according to three senior Syrian sources, two Lebanese security officials, and a diplomat with knowledge of the visit.
