UK's lowest payout for civilian death was £104.17

The Ministry of Defence paid out £688,000 for 289 civilian deaths between 2006-14, an average of £2,380.

But in one case, a family was paid just £104.17, less than others received for the deaths of a herd of donkeys.

The MoD said compensation was set by legal principles, including past and future losses and local customs.

Almost 7,000 compensation claims paid out by the British military during combat operations in Helmand, in Afghanistan, up until 2014 were analysed by the charity Action on Armed Violence (AOAV).

The youngest casualty was a three-year-old boy who, according to records, was "killed by shock" during a British mine clearance operation. At least 16 children were among the 289 civilian deaths.

Using data obtained under Freedom of Information requests, this is the first attempt to scrutinise the impact of British military forces on civilian lives in Afghanistan in this way.

Murray Jones from AOAV said: "The fact that a charity has had to scrutinise this data, rather than the British military themselves, is hugely concerning."

Compensation payments for civilians killed varied widely. In February 2008 a family received just £104.17 for a confirmed fatality and property damage.

There is no more detail given, but it is the lowest recorded sum for a civilian death.

In contrast, British forces paid out £110 for a lost mobile phone in Camp Bastion, £662 for the death of six donkeys after they "wandered on to a rifle range ", and £240 for damage caused to a property by an armoured vehicle.

Other payments linked to civilian deaths include £586.42 for the death of a 10-year-old boy in December 2009.

British forces also paid out £4,233.60 for four children "shot and killed by ISAF (International Security Assistance Force)" in the same month. There is no record of this incident in the English language media.

"So few of these deaths were reported on at the time that these casualties could easily be forgotten," said Mr Jones.
