AlHijjah 22, 1434, Oct 27, 2013, SPA -- The top U.N. official in the Democratic Republic of the Congo (DRC) Saturday strongly condemned the "unimaginable atrocities" committed by the Mayi-Mayi Cheka armed group during a spate of recent attacks in which some 34 civilians were brutally killed and warned against impunity for such acts. "These atrocities are unimaginable and are contradicting the values of humanity. This must have consequences. There cannot be impunity for such atrocious acts," Martin Kobler, head of the U.N. Organization Stabilization Mission in the DRC (MONUSCO), said in a statement. Kobler strongly condemned multiple attacks over the past few weeks perpetrated by elements of the Mayi-Mayi Cheka armed group, in some instances jointly with Raia Mutomboki combatants, in several villages of the territory of Masisi in the eastern Congolese province of North-Kivu. According to MONUSCO, at least 34 civilians, including 20 children, were brutally killed by the Mayi-Mayi Cheka elements in the different attacks in the eastern region.
