'Children handcuffed and shot' - ex-UK Special Forces break silence on war crime claims

Ex-UK Special Forces veterans give accounts of alleged war crimes committed by colleagues in Iraq and Afghanistan .

Witness: Killing of detainees "became routine" and some troops had a "mob mentality" Ex-SAS and SBS implicated for the first time in executions of unarmed and wounded people.

Ministry of Defence says it is "fully committed" to supporting the ongoing public inquiry.

Witnesses say more junior members of assault teams were told by more senior SAS operators to kill male detainees.

British and international law forbids troops from deliberately killing unarmed civilians or prisoners of war.

A former SAS operator also described learning of an operation in Iraq during which someone was executed.

The testimony supports previous reporting by Panorama that SAS squadrons kept count of their kills to compete with one another.

A spokesperson for Lord Cameron said the issues raised by President Karzai were about Nato forces in general and that specific incidents with respect to UK Special Forces were not raised.

A former director of service prosecutions said he hoped the public inquiry would examine the extent of Lord Cameron 's knowledge of alleged civilian casualties on British special forces operations.
