An internal investigation of the International Federation of Red Cross and Red Crescent Societies response to the recent Ebola epidemic uncovered an estimated $6 million of fraud committed by its workers:
The Red Cross has uncovered several cases of fraud by officials during efforts to combat the Ebola outbreak that struck West Africa in 2014-2016, estimating losses of $6-million (5.2 million euros). In a statement, the Geneva-based International Federation of Red Cross and Red Crescent Societies (IFRC) said it was "outraged", and said it would "ensure any staff involved are held to account."
[...] In Sierra Leone, it said it had found evidence of "likely collusion" between former IFRC employees and a bank, leading to a potential loss of $2.1-million. Overbilling and fake invoices by a provider of customs clearance services in Guinea cost the organisation $1.2 million, and two other investigations in the country are under way. The IFRC also said it had previously found that in Liberia, inflated prices for relief items and payroll costs had cost it $2.7 million.
