Rwanda arrests four top military officers KIGALI, Rwanda -- Rwanda's military has put under house arrest four top military officers over allegations of business dealings in the mineral-rich Democratic Republic of Congo, a statement from an army spokesman said on Wednesday. Three generals and one colonel were suspended during an investigation for "indiscipline," according to the statement, reported by the Associated Press and the BBC. One of the suspects under investigation is Brig. Gen. Richard Rutatina, who is head of military intelligence and an adviser to Rwandan President Paul Kagame. A BBC reporter in the Rwandan capital, Kigali, said the arrest came as a shock considering the rank of the officers. Also reported held were Lt. Gen. Fred Ibingira, chief of staff of the reserves force, Gen. Wilson Gumisiriza, division commander, and Col. Dan Munyuza, external intelligence chief. Rwanda's army, which has invaded Congo twice, has denied in the past looting the country's mineral wealth.
