A picture taken on September 5, 2011 shows the International Criminal Court's building (ICC) in The Hague where Ruto, seen as a potential presidential candidate in 2012, Kosgey and radio executive Joshua arap Sang will appear for a hearing. Judges must now decide whether there is sufficient evidence to put Ruto, 44, Kosgey, 64, and Sang, 35, on trial for their alleged roles in the post-poll violence in Kenya in which over 1,100 people died. The three senior Kenyan leaders face charges of crimes against humanity including murder, forcible transfer and persecution before the court in The Hague.
