TEHRAN (FNA)- The US-backed Syrian Democratic Forces (SDF) continue detention of civilians in Raqqa as it is faced with popular uprising against occupiers in the towns of al-Mansoureh, Hunaideh, al-Hamam and other parts of Western Raqqa.

Media activists in Raqqa reported that the SDF tortures its detainees in jails, adding that recently, one of the trubal leaders who had called for the Syrian army deployment in regions occupied by the SDF was killed under torture.

Also, the Arabic-language website of Sputnik quoted media activists as saying that a group of defected ISIL members who later merged with the SDF under the name of Oweis Qarani are responsible for torturing the jailed civilians.

According to the report, a large number of young Syrians have been killed under torture so far.

Hundreds of people were arrested by the SDF in the recent uprisings against the US-backed SDF in regions in Raqqa under the control of the Kurds.

Last month the Syrian Democratic Forces detained more than 1,300 Syrian citizens, most of them children, youth and women, in areas stretching from Abu Qabi to al-Tabaqa, South of Euphrates River.

A number of Arab members of SDF left the group after the US-backed militia arrested a number of Arab tribesmen in Raqqa.

Meantime, media activists in Raqqa were quoted as saying that the residents of Raqqa hoisted Syria’s national flag and printed graffiti against the US occupying troops and the SDF in several regions, including the town of Kadiran to West of Raqqa, calling for the Syrian Army rule over the region.

The SDF fighters have reportedly severely tortured a renowned tribal leader of Al-Tarn Tribe in the Western part of Raqqa after he in a statement called for the presence of the Syrian Army in the areas under the control of the US and the SDF.
