Speaking on condition of anonymity due to security concerns, the source said the troops, who described themselves as "Assad's soldiers", were later sent to Turkish security units for interrogation.

Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on pro-democracy protests -- which erupted as part of the "Arab Spring" uprisings -- with unexpected ferocity.
Since then, more than a quarter of a million people have been killed and more than 10 million displaced across the war-battered country, according to the UN.
The Syrian Center for Policy Research, however, put the death toll from the six-year conflict at more than 470,000 people.
