Rwanda marks 11th anniversary of genocide

Rwanda marks the anniversary of the 1994 genocide today with the beginning of a week of mourning for the more than 500,000 people who died in a frenzy of killing that remains fresh in the minds of the survivors.

For Catherine Umutoni, 27, April always brings tears and memories of her 13 relatives who were killed by Hutu extremists in 100 days of massacres.
