The unverified footage, which the extent of brutality exercised by the Takfiri militants operating inside Syria, shows a group of al-Qaeda-linked al-Nusra Front Takfiris blocking a main road inside Iraq.
They show in the film that they have come from Syria.
The militants stop a number of heavy trucks and start interrogating the drivers about their religion.
The frightened drivers claim to be Sunnis. Shortly afterwards, when they are found to be Alawites - a Shia offshoot sect - the Takfiris shoot them dead at close range. The trucks are later set on fire.
The video comes as Abu Mohammad al-Golani, a commander of the al-Nusra Front, has threatened to target homes of the Alawite community with rockets.
“On top of that we will prepare a thousand rockets that will be fired on their towns,” Golani said in an audio recording recently posted on YouTube.
Since the outbreak of the deadly unrest in Syria in 2011, several video clips have been released showing the grisly crimes committed by the US-backed terrorists against innocent civilians in the war-torn country.
Earlier this month, a gruesome video emerged on the Internet, showing foreign-backed militants in Syria setting three Syrian Kurds on fire.
The video, which was posted online on August 5, showed the al-Nusra Front militants pouring a flammable liquid on the hand-cuffed, blind-folded men who appear to be Syrian Kurd soldiers. The militants then pushed the three into a fire they had made.
According to reports, Western powers and their regional allies - especially Qatar, Saudi Arabia, and Turkey - are supporting the Takfiris.
The United Nations says over 100,000 people have been killed and a total of 7.8 million of others displaced due to the turmoil.
