this town thankyou.
You could even attach pictures or paste stories or link
BUT YOU MUST STAY ON TOPIC WHICH IS THE CHALENGE OF
The Armenian Genocide and Ethnic Cleansing in the Ottoman Empire Taner Akçam ... picture of Der Zor was noted above, characterized the area between Der Zor and Sabha (Sebka?) ...
You will find As-Sabkhah South east of Raqqa, but you will also find next store Sabkhawi there both along the euphrates river, that could have been Sebka instead, but more likely they were both once one town called Sebka, yet i am only guessing.
