Commemorations have begun in Rwanda to mark the 25th anniversary of the genocide that killed about a tenth of the population.
The country will mourn for 100 days, the time it took in 1994 for 800,000 Rwandans to be massacred.
Most were minority Tutsis, killed by ethnic Hutu extremists.
President Paul Kagame, who led the rebel force that ended the genocide, lit a remembrance flame at the memorial in the capital, Kigali.
