The unverified footage shows a group of al-Qaeda-linked al-Nusra Front Takfiris blocking a main road near the Iraqi border. 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.
