2 British and 2 US Troops Killed in Green on Blue Attacks

Whilst on patrol Wednesday night, two British soldiers were killed by a nonuniformed Afghan male.

Officials believe that he was a member of the Afghan Police.

Only a few hours later, early Thursday morning, two US personnel were shot down by someone wearing an Afghan National Police uniform.

Both incidents are being investigated as "green on blue attacks".

In 2012 alone, there have been forty-five deaths in thirty-four incidents of such attacks, that is more than every other year combined.

None of the four coalition troops have yet been identified, but the units of the British soldiers have been released.

They were a Royal Marine from 40 Commando Royal Marines and a female soldier from 3 Medical Regiment.
