US envoy Samantha Power

The U.S. Ambassador to the United Nations, Samantha Power, arrived in Guinea's capital Conakry on Sunday on a mission to see first hand how the global response is failing to stop the deadly spread of Ebola in West Africa, Reuters reported.
Power, who will also visit Sierra Leone and Liberia, said she hopes to gain a better understanding of what resources are missing so she can push other countries to offer more help.
The three West African countries are bearing the brunt of the worst outbreak of the hemorrhagic fever on record that the World Health Organization says has killed nearly 5,000 people. A small number of cases have also been reported in Mali, Nigeria, Senegal, Spain and the United States.
