Fresh details have emerged of the involvement of British forces in incidents in which Afghan civilians were killed or wounded.
The Guardian, which obtained the details from the Ministry of Defence through the Freedom of Information Act, said they raised questions about the conduct of three British units.
The Royal Marines, the Coldstream Guards and the Rifles were each said to have been involved in “clusters” of incidents in which civilians died or were wounded.
The details relate to 21 incidents between 2006 and 2009 which were referred to in thousands of leaked US military logs posted on the WikiLeaks website last year.
They disclose that the Coldstream Guards shot four civilians in Kabul over a three-week period in the autumn of 2007, killing two and wounding two others.
Royal Marines from 42 and 45 Commandos killed or wounded civilians eight times during a six-month period in late 2008 and early 2009, while the Rifles were involved in three incidents last year.
In one incident the Coldstreams opened fire on a mini-bus which failed to halt when they signalled for it to stop, killing one person and wounding two others. In another the son of an Afghan general was shot and killed when his car was said to have accelerated towards a Coldstream Guards patrol.
The incidents involving the Royal Marines included one in which a child was shot dead in a car believed to have been driving towards them at a time when a suicide bomber was reported to be in the area.
An MoD spokesman said: “We deeply regret all civilian casualties. Protecting the Afghan civilian population is a cornerstone of Isaf’s mission, and all British troops undergo comprehensive training on the strict rules of engagement.
“This contrasts directly with the attitude of the insurgents, whose indiscriminate use of suicide bombs, roadside explosive devices and human shields cause the majority of civilian deaths and injuries in Afghanistan.”
