"More than 120 members belonging to the elite regiment are currently in the war-torn country" covertly "dressed in black and flying ISIS flags," engaged in what's called Operation Shader – attacking Syrian targets on the pretext of combatting ISIS.

Maybe covert US special forces and CIA elements are involved the same way. During Obama's war on Libya, Britain deployed hundreds of Special Forces Support Group (SFSG) paratroopers – drawn from SAS (Special Air Service) and SBS (Special Boat Service) personnel.

Around 800 Royal Marines and 4,000 US counterparts were on standby to intervene on short notice if ordered.

The latest revelation comes two weeks after learning Prime Minister David Cameron last year approved British warplanes joining US ones in bombing Syria despite parliamentary rejection in August 2013.
