Ethnic tensions and political and economic corruption are rampant in Liberia, and dealing with these institutional problems is a monumental challenge for any outsider.

Former Liberian President Charles Taylor, wanted for war crimes by the international tribunal in Sierra Leone, was arrested on Wednesday in northern Nigeria on the Cameroon border. He was deported to Monrovia and from there transferred to UN custody in Sierra Leone. Just a day before his arrest he had disappeared from the villa in south-eastern Nigeria, where he had been living in exile since stepping down from power in 2003 as part of an arrangement brokered by AU, ECOWAS and other key international actors including the US to end 14 years of civil war in Liberia.
