LONDON: Commandos in Britain's elite Special Air Service (SAS) corps killed at least 54 Afghans in suspicious circumstances but the military chain of command concealed concerns, a BBC investigation said Tuesday, reports AFP.
Unarmed Afghan men were routinely shot dead "in cold blood" by SAS troops during night-time raids during the long war, and weapons were planted on them to justify the crimes, the four-year probe found.
Under UK law governing the armed forces, it is a criminal offence for a commanding officer to fail to inform the military police if they become aware of potential war crimes, the BBC noted.
Carleton-Smith, who retired last month as head of the British army overall, declined to comment to the BBC programme "Panorama", which said its investigation was based on court documents, leaked emails and its own journalists' travel to sites of the operations in Afghanistan.
The ministry of defence said prior investigations into the conduct of UK forces in Afghanistan found insufficient evidence to bring charges.
"No new evidence has been presented, but the service police will consider any allegations should new evidence come to light," it said in a statement to the BBC.
"The UK armed forces served with courage and professionalism in Afghanistan and we will always hold them to the highest standards."
After-action reports showed other officers were surprised at the high casualty rate being inflicted by the unit, when none of the SAS troops reported injuries in apparent firefights with Taliban militants.
"Too many people were being killed on night raids and the explanations didn't make sense. Once somebody is detained, they shouldn't end up dead," one senior officer at special forces headquarters told Panorama.
"For it to happen over and over again was causing alarm at HQ. It was clear at the time that something was wrong."
