The international aid charity struggled to find a company willing to cover the director of a humanitarian relief project working in refugee camps across the south and west of the province.
Several insurers told the charity that the project director, whose name is being kept secret for security reasons, was considered to be too high a risk because of his nationality.
Just days before he was due to start his post, Cafod arranged insurance with Banner Financial Services, which has a policy of not discriminating on grounds of national identity.
"Without this cover we would have been in an enormously difficult position with this particular employee," said Martin Kelly, personnel adviser at Cafod. "The only alternative would have been for us to self-insure and bear the risks of accident cover and medical emergencies ourselves."
Robin Williams, a director at Banner, said: "If you say to most insurers that there is an American going to a war-torn region, then the stock answer will be negative."
