Sadistic ISIS executioners with a fondness for “Mission: Impossible” hung prisoners upside down from meat hooks and then slit their throats inside a Syrian slaughterhouse, a newly released video shows.

About two dozen people were killed during the sickening 12-minute video released by Islamic State sickos, according to the human-rights group Raqqa Is Being Slaughtered Silently.

The humanitarian group’s founder, Abu Mohammed, described it as “the worst video we saw” and added that the victims were butchered “like sheep.”

The footage comes on the heels of Eid al-Adha — a three-day Islamic holy period in which livestock is slaughtered and the meat is donated to the poor.

The video features pictures of past ISIS atrocities and clips from “Mission: Impossible — Rogue Nation” showing actors Tom Cruise and Simon Pegg.

The movie images are believed to represent spying that the killers contend their victims were engaging in on behalf of US coalition forces, according to the Daily Star.

Other pictures show a burly jihadist carrying two prisoners — one in each arm — to their horrible demise. The brute slashes their jugular veins over a metal grate and watches as the blood drains away.

Another image shows the executioner wielding a butcher knife as prisoners in orange jumpsuits are corralled in the slaughterhouse with their hands bound behind their backs.

The footage also shows prisoners hanging upside down by their feet from the hooks with their throats slashed, while others await the same fate as they are lifted into a similar position.

Meanwhile, German authorities were probing three suspected ISIS jihadists arrested Tuesday for their possible involvement in last November’s Paris terror attacks, which killed 130.

German Interior Minister Thomas de Maiziere said the three Syrian nationals are a “sleeper cell” with ties to the same smugglers who helped import the Paris terrorists.
