While speaking during a parliamentarian hearing British Foreign Minister William Hague said British officials are working closely with coalition forces and Afghan security forces to reduce insider attacks on NATO troops.
William Hague said cultural awareness educations and monitoring of the Afghan security forces have also been doubled to reduce the insider attacks.
He said strict measures are taken while recruiting new Afghan security forces and also intelligence activities have been doubled.
According to British Foreign Minister William Hague Afghan security force are also largely threatened by insider attacks since they are gaining more responsibilities to fight the insurgents on the frontline.
However Mr. Hague said such attacks will not force Britain and other allied nations to consider a change in their policy in Afghanistan.
This comes as four Afghan police officers were killed by their comrades in southern Helmand province of Afghanistan on Friday in latest wave of insider attacks.
Mohammad Toryalai district security chief for Greshk in Helmand said the incident took place during a shift change in a security check post in this district and the assailant police officers managed to flee the area.
In the meantime two British troops were shot dead by an individual in Afghan police uniform in this province last week.
Nearly 50 NATO troops including 11 British troops have been killed following green on blue attacks in Afghanistan during the year 2012.
