Two British NATO soldiers have been shot dead in the Helmand province Afghanistan by a man wearing a local police uniform, according to the International Security Assistance Force. At the moment no more details as to the soldiers names, battalion or where they are from are available. But the Taliban have admitted responsibility for the attack.

Brigadier General Gunter Katz speaking at a press conference confirmed the incident.

The Afghan conflict had seen a surge in insider attacks this year, with more than 50 ISAF troops killed by their colleagues in the Afghan army and police. And this follows the deaths just last week of two British soldiers, a female army medic and a Royal British Marine who were killed by insider fire or a green on blue attack while on patrol.

As this worrying trend continues, General John Allen from ISAF offered a sobering view on the deaths, saying that just as home-made bombs were the signature weapon of the Iraq war, in Afghanistan "the signature attack that we're beginning to see is going to be the insider attack."
