Bone fragments are seen in a barrel of the cremated remains of Ebola virus victims in Boys Town, January 9, 2015. The furnace has been extinguished at a crematorium for victims of the deadly Ebola virus near Liberia's capital Monrovia but a row of barrels filled with ash and charred bone are a reminder of the darkest days of the outbreak. More than 3,500 people died of Ebola here over the past 10 months but now there are just 10 confirmed cases according to the government, which hopes that figure may fall to zero by the end of next month. With the worst seemingly past, Liberia is gradually starting to deal with the loss, but for many people it is hard to properly mourn loved ones whose bodies may never be recovered.
