A kidnapped British aid worker has been rescued in Afghanistan in what David Cameron has described as an "extradordinarily brave, breath-taking" operation by coalition forces. Helen Johnston, 28, was freed along with three other hostages - Kenyan national Moragwe Oirer and two Afghan civilians - in an early morning raid. They had been abducted on May 22 in the northeast province of Badakhshan. The Prime Minister said he authorised the rescue on Friday afternoon due to increasing concerns over the safety of Ms Johnston and the other hostages. The operation involved a number of British troops, helped by Isaf forces as well the Afghan government, and involved a "long route march" without being discovered. Mr Cameron confirmed all four hostages are safe, no British troops were injured in the raid - and a number of Taliban and hostage-takers were killed. Source: The Coming Crisis
