A British sniper has killed a senior Isis fighter with a "one in a million" night-time shot from nearly a mile away, it has been claimed.
The unnamed SAS marksman is said to have killed the terrorist with a "head shot" close to the Syrian border having been given a window of just 15 seconds.
He is understood to be a sergeant with the SAS G-Squadron and a veteran of operations in both Iraq and Afghanistan, where he is said to have recorded as many as 100 kills, the Daily Mail reports.
• Crack shot: Inside the sniper's mind
According to the Daily Star Sunday, he is believed to have used a US-made McMillan TAC-50 sniper rifle as he targeted the fanatic from more than 1,500m away as he arrived at a safe house in a village.
The trooper is reportedly part of a counterterrorism drive in Iraq and Syria, which has been operating since the beginning of the year.
A source told the newspaper that the village in question was under Isis control making a more preferable "capture mission" impossible. The exact location has not been revealed.
"The SAS team had hoped that the Isis commander would arrive during the day because a night shot was regarded as too dangerous," the source said.
"But as evening approached the team realised that they were going to have to either abort or go for a night shot. The sniper said he wanted to take the shot and was given a 'go order'."
The sniper had 15 seconds to take his shot as the extremist pulled up in a car. The source said the extremist was killed instantly after being shot in the back of the head.
The Ministry of Defence declined to comment when contacted by MailOnline this morning.
