Some 800,000 Rwandans, mainly Tutsis, were murdered in a 100-day period following the killing of the Hutu president of Rwanda, Juvenal Habyarimana.
800,000 were killed in the 1994 Rwandan genocide.
The presidential guard quickly murdered the political opposition and enacted a pre-planned campaign of slaughter that spread across the country. Soldiers, government officials and business leaders organised the killings and were joined by a Hutu militia, the Interahamwe.
The international community did little to stop the killings and the slaughter was brought to end by the military defeat of the government by the Rwandan Patriotic Front, a Tutsi-led rebel group.
6 April 1994: President Habyarimana and Burundian President Cyprien Ntaryamira are killed when the Rwandan leader's plane is shot down as it is about to land at Kigali Airport. Hutu extremists opposed to the Arusha Peace Accords are believed to be behind the attack.
7 April: The Rwandan armed forces and Interahamwe militia begin the systematic killing of Tutsis and moderate Hutus. UN forces, unwilling to breach their mandate, fail to intervene. 10 Belgian UN peacekeepers are killed.
8 April: The Tutsi Rwandan Patriotic Front (RPF) launches a major offensive to end the killings and rescue 600 of its troops based in Kigali under the Arusha Accords.
9-10 April: French, Belgian and American civilians are rescued by their governments.
11 April: The International Red Cross (IRC) estimates that tens of thousands have been slaughtered. UN soldiers protecting 2,000 Tutsis at a school are ordered to withdraw to Kigali airport. Most are killed after their departure.
14 April: Belgium withdraws its troops from the UN peacekeeping force in Rwanda.
15 April: Slaughter of thousands of Tutsis gathered at Nyarubuye Church seeking protection.
21 April: The UN cuts the level of its forces in Rwanda by 90% to just 270 troops. The IRC estimates the dead could now number over 100,000.
30 April: The UN agrees a resolution condemning the killing but omits the word 'genocide'. Tens of thousands of refugees flee into neighbouring Burundi, Tanzania and Zaire.
Mid-May: The IRC estimates that 500,000 Rwandans have been killed.
17 May: The UN Security Council issues a fresh resolution saying that 'acts of genocide may have been committed'. It also agrees to send 5,500 troops with new powers to defend civilians, however deployment is delayed by disagreements between the US and UN over the financing of the operation.
22 May: RPF forces gain control of Kigali airport and Kanombe barracks, and extend their control over the northern and eastern parts of Rwanda.
22 June: With arguments over the deployment still continuing, the UN authorises an emergency force of 2,500 French troops under Operation Turquoise to create a 'safe' area in the government-controlled part of Rwanda. The killing of Tutsis continues in the 'safe' area despite the presence of the French.
4 July: The RPF takes control of Kigali and the southern town of Butare. Its leadership claims it will form a government on the basis of the Arusha Accords.
13-14 July: Refugees fleeing the RPF advance in north-western Rwanda flood into Zaire. Approximately 10,000-12,000 refugees per hour cross the border into the town of Goma. The massive influx creates a severe humanitarian crisis, as there is an acute lack of shelter, food and water.
18 July: The RPF announces that the war is over, declares a cease-fire and names Pastor Bizimungu as president with Faustin Twagiramungu as prime minister
