Rwanda's Supreme Court in Kigali on Friday sentenced opposition figure Victoire Ingabire to 15 years in jail on appeal, increasing her prison term from eight years for conspiring against the authorities. The court upheld a previous conviction for terrorist conspiracy and minimising Rwanda's 1994 genocide, in which at least 800,000 people were killed by troops and extremists of the Hutu majority. Ingabire, a Hutu, was also found guilty of spreading rumours to incite violence.
