Rwandan genocide: A survivor's story
Rwanda is holding a week of official mourning to mark the 20th anniversary of the country's genocide.
On 6 April 1994, a plane carrying then-President Juvenal Habyarimana - a Hutu - was shot down, killing everyone on board. Hutu extremists blamed the Tutsi rebel group the Rwandan Patriotic Front (RPF), and immediately started a well-organised campaign of slaughter.
The RPF said the plane had been shot down by Hutus to provide an excuse for the genocide.
Between April and June, an estimated 800,000 people - mostly ethnic Tutsis and moderate Hutus - died at the hands of Hutu extremists.
Liliane Umubyeyi, who is now 35, witnessed her family being slaughtered by armed Hutus and was gang-raped, but survived. She told her story to Newsnight.
