Former members of the British Special Forces described war crimes allegedly committed by British soldiers in Afghanistan and Iraq, dating back to a decade.
More than 30 witnesses serving with special forces soldiers or with special forces or with special forces broke the silence of the BBC’s Panorama program and spoke about the illegal killing and execution of detainees, including children, during the invasion of the two countries.
David Cameron, the prime minister from June 2010 to November 2013, is now a time of review of the public investigation by a special forces led by judges, and has repeatedly realized concerns about night raids and killings raised by then-Afghan President Hamid Karzai.
A Cameron spokesman said: "Any advice (his) to cover up allegations of serious criminal misconduct is nonsense".
Special aviation services and special ship services of the Navy, the top special forces of the UK, are the center of testimony.
"They put a little boy on and shot him," recalled a veteran who served in elite soldiers in Afghanistan. "He was obviously a child and was not even close to combat age."
The veteran said the killing of detainees was “a routine”, adding that soldiers would remove plastic handcuffs and plant weapons from their bodies, making them look like fighters in photos taken from the scene.
Another veteran of the Navy's Special Forces said some service personnel exhibited "barbaric" and "psychotic" behavior because they believed the law could not be reached.
One former soldier described the killing as possible becoming “addiction” because some soldiers were “intoxicated by the feeling” in Afghanistan.
"In some operations, the troops will go into hotel-type buildings and kill everyone," he said. "They will go in and shoot everyone, and go into there.
Witnesses said even injured people who did not pose a threat to anyone were executed for violating international law.
A former special forces operator said that an unarmed Iraqi man had never been executed and had never been properly investigated, adding that the senior commander knew about the issue before it was deployed to Afghanistan.
The BBC also obtained new video evidence showing that the squadron has been competing with others.
A former colleague tried to be killed in every operation and became "notorious" for killing dozens of people, a veteran said.
Another veteran said that "everyone knows" testimony about the killing of the British Special Forces Command showed that officials would forge post-operative reports to avoid scrutiny.
