Opposition leaders have accused Kagame of ordering the assassination of Rwanda’s former spy chief Patrick Karegeya who was found dead, possibly strangled, in his room at a Johannesburg hotel Wednesday, Jan. 1, 2014, claiming the death follows a pattern of assassinations ordered by Kagame. Rwanda's government has vehemently denied such charges. (AP Photo/Sayyid Azim, File)
