KIGALI, Rwanda (AP) — Displaying both pride and pain, Rwandans on Monday marked the 20th anniversary of a devastating 100-day genocide that saw packed churches set on fire and machete-wielding attackers chop down whole families from a demonized minority.

Bloodcurdling screams and sorrowful wails resounded throughout a packed sports stadium as world leaders and thousands of Rwandans gathered to hear of healing and hope.
