A single shot from a British marksman’s rifle killed a suicide bomber in Afghanistan and five of his fellow terrorists, as they were about to launch a bloody attack, The New York Post reports, based on the British Telegraph.

According to the report, the British sniper, who was firing from an amazing 930 yards (850 meters) away, shot the trigger switch of the suicide bomber’s lethal vest, killing the attacker and the five others in the ensuing blast.

“The guy was wearing a vest. He was identified by the sniper moving down a tree line and coming up over a ditch, He had a shawl on. It rose up and the sniper saw he had a machine gun,” said Lt. Col. Richard Slack.

“They were in contact and he was moving to a firing position. The sniper engaged him and the guy exploded. There was a pause on the radio and the sniper said, ‘I think I’ve just shot a suicide bomber.’ The rest of them were killed in the blast.”

The unidentified 20-year-old soldier, a lance corporal in the Coldstream Guards (the oldest regiment in the British Regular Army in continuous active service) was credited with stopping a potentially devastating attack by the Taliban in Kakaran in southern Afghanistan.

British forces later found a second suicide vest packed with 40 pounds of explosives nearby, according to The New York Post.

The incredible feat of marksmanship happened last December but was only recently disclosed to the public.

The sniper, who was using the British army’s most powerful sniper weapon, the L115A3 gun, had previously managed to kill a Taliban machine-gunner from 1,465 yards (1,340 meters) away with his first shot on the tour of duty, according to the report.

This incident reminds of one of another recent accidental blast, when at least 22 Iraqi terrorists were killed during a training exercise, after a commander instructing would-be suicide bombers accidentally detonated himself.

The terrorists had been filming a propaganda video before a planned suicide bombing when the vehicle exploded. Instead, the terrorists filmed their own deaths.

Such “work accidents” are not uncommon. Several weeks ago, a leader of the Sinai-based Ansar Bayt al-Maqdis terrorist group died in a car crash, which detonated the explosives he was transporting.
