According to British media reports, Special Air Service (SAS) operators who are participating in the final push against the remnants of the Islamic State (ISIS) came upon a massive grave filled with severed heads. The SAS operators found the grave near ISIS’ last enclave in Baghuz, which is located on the banks of the Euphrates River in eastern Syria.

The grave is described as numerous trash cans containing more than 50 heads of executed Yazidi women who had been used as sex slaves by the perverse terrorists. Press representatives from the Syrian Democratic Forces (SDF), which is mostly comprised of Kurdish Peshmerga, seconded the reports stating that a massive grave with dozens of headless women’s corpses was found by advancing coalition forces.

Throughout ISIS’ reign of terror, which began in 2014, the Yazidis suffered disproportionately. In the initial stages of the jihadi blitzkrieg that took them close to Baghdad, more than 3,000 Yazidis were killed while thousands more were enslaved. The United Nations (U.N.) characterized the killings as genocide.

The reports state the SAS force supporting the final assault against ISIS is a 65-man Troop from B Squadron. The 22 SAS Regiment is composed of four Sabre Squadrons (A, B, D, G), each containing a headquarters element and four troops. Every troop specializes in a different spectrum of special operations insertion methods (air, water, ground mobility, and mountain). Two Territorial (Reserve) Army SAS regiments (21 SAS and 23 SAS) provide additional flexibility to British commanders, who can assign secondary tasks. Those may include foreign internal defense, a mission the SAS operator who single-handedly stopped the terrorist attack in Kenya was doing, and the territorial SAS components to preserve the active duty unit for more important and time-sensitive operations.

There are around 500 ISIS fighters left in an area less than one-fifth of a square mile that consists of numerous small hamlets and farmland. In an attempt to slow down the coalition’s advance, ISIS fighters have been using snipers and suicide attacks – mostly vehicle-borne improvised explosive devices (VBIED). More perversely, they are using civilians as human shields to escape from the dreaded coalition airstrikes.

Mervan Rojava, an SDF public affairs representative, said: “All the tunnels they have dug for a moment like this aren’t really useful because they control a very small patch of territory. But they are taking advantage of sending a large number of suicide bombers toward us. This is something that they have done in previous battles, too. But this time it is challenging for them because they have nowhere else to go.”
