A BRITISH solider who ran our of ammo during a gruelling six-hour gun battle with ISIS reportedly used a spade to decapitate a jihadi.

The SAS trooper is said to have picked up the shovel to use as a weapon when the fighter charged and cut-off his head with one blow.

The Daily Star on Sunday say he then grabbed the finished fanatic's weapon to fend off more militants as the battle continued.

The sergeant - a veteran of dozens of battles - was on patrol in eastern Afghanistan when they were ambushed by ISIS fighters, according to The Star.

Sources told the paper the fire fight, which happened six week ago, came after a meeting between the British special forces and former members of the Taliban fighting on the side of the Afghan government.

The SAS squad was forced to take cover in a farm as wave after wave of extremist fighters attacked.

The soldiers were locked in the vicious gun battle for six hours and began to run low on bullets.

They radioed their base to call for air support but could not determine if their message got through.

A source told the Star: “The SAS thought they had seen their last day.

“They made a pact that they wouldn’t be taken alive and vowed to fight to the death.

“Capture would mean torture and a filmed execution and they weren’t prepared to let that happen.

“They made every bullet count and when they ran low on ammo they waited for the jihadis to get close enough so they could be killed with grenades or using rifles as clubs – that was when one of the SAS managed to kill a man with a spade.”

Luckily two US Apache helicopter gunships appeared and forced the insurgents to retreat.
