The war that has claimed more victims than any other since world war two is reigniting at potentially horrific cost. Several million Congolese died before international efforts to broker peace began to bear fruit in 2003. The United Nations' largest peacekeeping force has since prevented a legacy of localised conflicts regaining nationwide momentum, although atrocities have continued on a monstrous scale. This time, however, the pattern of fighting, and of bellicose statements emanating from neighbouring capitals, bears alarming similarities to events that led in the past to a devastating regional war.
Ethnic Tutsi rebels allied to neighbouring Rwanda are poised to capture the eastern city of Goma, where UN forces have their principal base. More than a million displaced villagers risk being cut off from aid. Congolese government troops are on the run and Kinshasa is appealing to Angola to intervene on its behalf. History is repeating itself. Britain and America - as Rwanda's principal western allies - risk playing a proxy role in a possible bloodbath and collapse of the UN mission if they fail to use their leverage.
