An attack by suspected Ugandan rebels near Beni in the eastern Democratic Republic of Congo has left 15 people dead, the mayor of the town said Sunday. Some of those who fled after Saturday's attack were seriously injured, meaning that the death toll could rise, Nyonyi Bwana Kawa told dpa by phone. Army spokesman Olivier Hamuli confirmed that civilians had been attacked in the region, but said the authorities were still verifying the number of people killed.
