LONDON - A British sniper has killed an Islamic State (Isis) executioner as he prepared to kill several hostages by shooting a fuel tank on his back and incinerating him.

It's reported the marksman fired a single shot from 1,500 metres as the terrorist was about to use a flame thrower.

The bullet caused such a huge fireball, it also killed three other Isis members standing next to the target, who were filming the execution.

Sources say the executioner had been on a "kill list" drawn up by American forces.

In an area near Raqqa in Syria the target was preparing to execute 12 prisoners with a flame thrower when the British sniper took aim.

With a single round from a Barrett .50 calibre sniper rifle from a distance of 1,500m the marksman hit the fuel tank on his back causing a huge explosion.

Shortly afterwards, the prisoners, thought to be civilians, were freed by British and US Special Forces.
