The Islamic State terrorist group has released a disturbing new propaganda video showing its fighters carrying out yet another mass execution by beheading Syrian rebels and placing their heads on spears.
Al Arabiya reports that in the video, the jihadists threaten bloodshed against any Muslims attempting to join US-backed groups seeking to overthrow the Assad regime in the war-torn Middle East.
Two fighters talking in the video, both dressed in black, announce the group will not tolerate anything other than an Islamic State-run Syria, before members of the Free Syrian Army are brutally murdered.
The 19-minute video starts with a statement in English, saying: "In this video production is a presentation of some recorded scenes documenting the source of the program to train the sahwat vetted by America in Jordan under the wings of the Crusader coalition forces.
"This is a small portion of what the sahwat left behind to become ghanimah in the hands of the Khilafah's soldiers after they failed to advance on the city of Albu Kamal and their soldiers were either killed or driven out. And to Allah belongs all praise and favor."
After accusing the US of trying to take over the Middle East, the jihadists throw members of the Free Syrian Army to the ground in the desert before beheading them with small knives. Then, the men's heads are removed from their bodies and placed on spears.
The 19-minute long propaganda video was released by a group calling themselves "Wilayat Furat in Iraq" (translated to the State of the Euphrates) who have pledged allegiance to ISIS.
The terrorist group proclaimed a caliphate over parts of Iraq and Syria in 2014 but has lost a significant amount of territory since then to U.S.-backed offensives, though it still controls oil wells on Syrian land.
Religious minorities are among its main targets, and over the past two years, the group has released a number of propaganda videos showing its fighters using brutal methods to torture and punish those who it considers to be its enemies.
Last month, ISIS released a video, titled "The Making of Illusion", showing men accused of spying for the United States being slaughtered like lambs and hanging upside down from meat hooks inside a slaughterhouse.
In September, the Pentagon announced Wa'il Adil Hasan Salman al-Fayad, an ISIS leader who oversaw the militant group's propaganda, was killed in Syria in an airstrike carried out by the US-led coalition.
The Pentagon said Wa'il was minister of information and a prominent member of Isis's senior shura council, or leadership group. "Wa'il oversaw Isil's production of terrorist propaganda videos showing torture and executions," reads the statement. "He was a close associate of Abu Muhammad al-Adnani, the Isil spokesman and leader for plotting and inspiring external terror attacks."
