Shocking images have emerged of the latest barbaric act by ISIS barbarians — turning a captive into an airborne bomb.

A Syrian soldier was bound tightly and kept ramrod straight with wooden planks — apparently to make him aerodynamic — before an explosives-filled helmet topped by an impact fuse was placed on his head.

He was then thrown off a building in ISIS-controlled territory in the Yarmouk district near Damascus, where his decapitated, mangled body mixed with the surrounding rubble, the UK’s Sun reported.

The ghoulish act, shown on the terror group’s propaganda channel, was believed to be in retaliation for devastating airstrikes by Syrian and Russian forces.

A recent UN Security Council report said the jihadists have held onto several Syrian areas, including Yarmouk.

Secretary-General Antonio Guterres said ISIS also remains a threat in Deir el-Zour, Hasakah and the nearby Qadam neighborhood of the capital.

Meanwhile, more than three dozen Syrians held for years by al Qaeda-linked insurgents were released Tuesday as part of a deal to hand areas around Damascus back to the government, the UK’s Metro reported.
