The Syrian Observatory for Human Rights(SOHR), said that seven prisoners belonging to mercenaries managed to escape from a prison of the Turkish-backed military police in the town of al-Rai in the northern suburb of Aleppo.
SOHR explained that after the escape of mercenaries Ahrar al-Sherqiya managed to kill two of them and arrest others.
No mention was made of how the mercenaries escaped, but it is clear that the collabration between the Turkish Government and DAESH is strong. It has been seen in mainland Turkey that such prisoners have walked free, therefore it is a possibility that the prisoners were let go.
