Rwandans gather on Sunday to commemorate the lives of 800,000 Tutsi and moderate Hutus murdered during the Rwandan genocide, a three-month-killing spree that began 25 years ago.

The ceremony marks the beginning of a week of events to honour the dead. Rwandan President Paul Kagame layed a wreath at Gisozi genocide memorial site, where over a quarter a million of people are buried.

In the afternoon, officials join around 2,000 people in a “walk to remember” from parliament to the national soccer stadium, where candles will be lit in a night vigil.

At least 10 heads of state attend the event. Canadian Governor General Julie Payette and European Commission President Jean-Claude Juncker also attended.

The 100 days of slaughter began on April 6, 1994, after President Juvenal Habyarimana and his counterpart Cyprien Ntaryamira of Burundi – both Hutus – were killed when their plane was shot down over the Rwandan capital. The attackers have never been identified.

The attack mobilised Hutu government soldiers and allied extremist militia, who orchestrated the genocide to exterminate the Tutsi minority.

In villages across the densely populated country, neighbour turned on neighbour as men, women and children were hacked to death, burned alive, clubbed and shot.

As many as 10,000 people were killed daily. Seventy percent of the minority Tutsi population was wiped out, and over 10 percent of the total Rwandan population.

The fighting ended in July 1994 when the Rwandan Patriotic Front (RPF), a Tutsi-led rebel movement led by Kagame, swept in from Uganda and seized control of the country.

Official policy is to strongly discourage any talk of ethnicity, but the opposition says the tight control of the media and political sphere is also used to stifle dissent, something the government denies.
