"On a summer afternoon in 1994, David Guttenfelder took a taxi from the Rwandan capital Kigali to the nearby region of Bugesera. He walked inside the Ntarama Church and began taking photographs of people who had been murdered by their neighbors. They had come to the small, red-brick church from all over the area seeking refuge—just as their parents and grandparents had come in the past when violence broke out between the ethnic majority Hutus and minority Tutsis. But this time the church, like many others in Rwanda during the genocide, became a killing ground.

Thousands of bodies—old men and women, young men and women, boys and girls, toddlers and infants—filled the entire sanctuary. “People piled on top of one another, four or five deep, on top of the pews, between the pews, everywhere,” he said.
 
In this archival photograph taken in 1994, survivors of a massacre in Nyakizu, Rwanda, stand outside the Cyahinda parish church where villagers said 4,000 to 5,000 people were killed."
