Rwanda has begun a week of official mourning to mark the 20th anniversary of the country's genocide.

At least 800,000 people, mostly ethnic Tutsis and moderate Hutus, died at the hands of extremists.

Monday's events included a wreath-laying ceremony at the national genocide memorial, followed by the lighting of a flame at the Amahoro Stadium in the capital, Kigali.

Speaking to dignitaries and members of the public gathered in the stadium, President Paul Kagame said: "We did not need to experience genocide to become better people. It simply should never have happened."
