Abu Yazan al-Shami is an ISIS mercenary prince for nearly four years and was in the Syrian province of Deir ez-Zour.
About a year ago, he was imprisoned in the central prison of al-Ra'i city in the northern Aleppo countryside, which occupied by the Turkish army and its mercenaries.
According to local sources, he was released from prison.
No information has been obtained on his whereabouts.
On August 18, 2017, the Turkish occupation and its mercenaries occupied the city of Al-Ra'i, after a handover between them and ISIS mercenaries.
