They were on their way to carry out a terror attack at a nearby town, in which they planned to detonate their suicide vests amongst hundreds of civilians – causing mass deaths.

However, the SAS veteran wiped out all three of the extremists, as well as two ‘guards’ who were supposedly in place to keep a look-out and protect them from military forces.

The sniper shot the first jihadi in the chest as he walked out of the factory, which caused his suicide vest to detonate, killing him instantly – as well as two ISIS ‘guards’ who were sat in a nearby car.

The second ISIS militant was wiped out by a shot to the head, while the third was also killed when the sniper’s bullet struck his suicide vest and caused it to detonate.
