British special forces are back at war in Afghanistan, fighting both the so-called Islamic State terrorists and the Taliban, according to Mirror.

Just a year after David Cameron said the war was over, members of the SAS and SBS along with US special forces are taking part in military operations almost every night as the insurgent forces close in on the capital Kabul.

British troops are supposed to be just advisers to the Afghanistan special forces, who they have spent years training.

But senior defence sources say that in reality the troops are planning and leading counter-terrorist strike operations.

One source said: “In the last six months the British special forces have gone from training Afghan commando units to kicking down doors and arresting Taliban suspects. There have been some pretty hairy firefights but fortunately no casualties.

“The Afghan Special forces are enthusiastic amateurs but they do not have the ability to plan and execute counter-terrorist operations.”
