TEHRAN, Young Journalists Club (YJC) - The so-called Syrian Observatory for Human Rights said a car rigged with explosives was detonated remotely in the town of al-Shuhayl, close to an oil field, which serves as a base for the so-called Syrian Democratic Forces (SDF).
The Britain-based group added that six members of the Kurdish-led SDF were also killed as they escorted the workers.
Activists with relatives in the area said many of the young men in the blown-up minibus had come from work in the nearby al-Omar field.
Video footage published on social media networks purportedly showed bodies lying on the ground following the attack.
No group has claimed responsibility for the attack yet, but it bears the hallmark of attacks carried out by the Daesh Takfiri terror group.
Earlier, the observatory reported that around 150 Daesh terrorists and their family members had been handed over to Iraq.
It said the relatives were taken from the eastern Syrian village of Baghouz to Iraq in trucks belonging to the US-led coalition purportedly fighting Daesh.
Iraqi Prime Minister Adel Abdul-Mahdi said on Tuesday that he was concerned about developments in neighboring Syria, where Daesh terrorists have lost their last stronghold on the eastern bank of the Euphrates River, and are fleeing in droves towards desert areas in Iraq’s western province of Anbar.
Massive car bomb in Syria's Afrin
Also on Thursday, several people suffered injuries when a massive blast hit Syria's Kurdish-populated northwestern city of Afrin.
The explosion occurred as a car bomb was detonated near Dirsem Hospital following a military parade by members of the so-called Free Syrian Army, according to the observatory.
The London-based observatory added that some of the injured were in critical condition.
Syria has been gripped by foreign-backed militancy since March 2011. The Syrian government says the Israeli regime and its Western and regional allies are aiding Takfiri terrorist groups wreaking havoc in the country.
