As well as dismantling the refugee camps, Kagame began planning a war to remove Mobutu. Mobutu had supported the "genocidaires" based in the camps and was also accused of allowing attacks on Tutsi people within Zaire. The Rwandan and Ugandan governments supported an alliance of four rebel groups headed by Laurent-Désiré Kabila, which began waging the First Congo War. The rebels quickly took control of North and South Kivu provinces and then advanced west, gaining territory from the poorly organised and demotivated Zairian army with little fighting. They controlled the whole country by May 1997. Mobutu fled into exile and the country was renamed the Democratic Republic of the Congo (DRC). Rwanda fell out with the new Congolese regime in 1998 and Kagame supported a fresh rebellion, leading to the Second Congo War. This lasted until 2003 and caused millions of deaths and severe damage. A 2010 United Nations report accused the Rwandan Patriotic Army of wide-scale human rights violations and crimes against humanity during the two Congo wars, charges denied by the Rwandan Government.
