A British man shot dead in Afghanistan has been named as Richard Adamson, a manager for private security firm ArmorGroup.
A spokesman for the company said Mr Adamson, a former Royal Marine Warrant Officer, died of gunshot wounds inflicted by unknown assailants.
Mr Adamson's relationship with Afghanistan spanned more than 20 years and he was described as having been a "true friend" of the country. Next of kin have been informed.
Mr Adamson died as a result of an incident that took place in mid-afternoon Afghan time in the centre of Kabul.
Zemari Bashary, an Afghanistan Interior Ministry spokesman, said that two Afghan men had been arrested on suspicion of the attack that killed him.
Mr Bashary said that both suspects are also employees of ArmorGroup, a private security firm that assists national governments, multinational corporations and international peace organisations in hostile environments.
But the London-based firm described the assailants as "unknown", with a spokesman adding that they did not know if they were employees of the firm.
Mr Adamson, said to be in his 60s, was a former Royal Marine Warrant Officer with 20 years' service. He was described as having a wealth of experience working with humanitarian agencies.
He joined ArmorGroup in 2002 and was responsible for managing client contracts in support of the Afghanistan reconstruction effort.
In 2003, the firm was awarded the contract to protect British Government personnel in Afghanistan, a contract that was renewed last November.
