The Six-Day War (French: Guerre des Six Jours) comprised a series of armed confrontations between Ugandan and Rwandan forces around the city of Kisangani in the Democratic Republic of the Congo from 5 to 10 June 2000. The war formed part of the wider Second Congo War (1998-2003).
Kisangani was also a scene of violence between Rwandan and Ugandan troops in August 1999 and 5 May 2000. However, the conflicts of June 2000 were the most lethal, and seriously damaged a large part of the city, with more than 6,600 rounds fired.
According to Justice et Libération, a human-rights organisation based in Kisangani, the violence caused around 1,000 deaths and wounded at least 3,000, the majority of them civilians.
The conflict is called the "Six-Day War" not only due to its literal six-day duration but also because it shared the same dates as the Six-Day War between Israel and Arab states in 1967.
