Uganda has protested to Germany over the arrest of a Rwandan government official accused of involvement in the assassination of a former Rwandan president, a Ugandan official said Friday, according to dpa. Rose Kabuye, chief of protocol to Rwandan President Paul Kagame, was arrested in Frankfurt Sunday on a French warrant. She is suspected of having been involved in the assassination of Hutu president Juvenal Habyarimana - an act that sparked the 1994 genocide of up to 800,000 Tutsis and moderate Hutus. "We have sent a protest note to the Germany embassy here," Uganda's permanent secretary in the foreign ministry, James Mugume, told Deutsche Presse-Agentur dpa. "The arrest was an arbitrary violation of the sovereignty of the country." The arrest of Kabuye has sparked widespread anger in Rwanda.
