In April 1994, a sinister call was broadcast over radio stations across Rwanda, triggering the start of 100 days of genocide that left more than one million people dead. Henriette Mutegwaraba heard that call over the radio.

“Every time I talk about it, I cry,” she told UN News, describing how propaganda spread messages of hate that sparked a deadly wave of unspeakable violence. She lost 60 family members and friends in the genocide.

Ahead of the UN General Assembly’s commemoration of the International Day of Reflection on the 1994 Genocide against the Tutsi in Rwanda, Ms. Mutegwaraba spoke with UN News about hate speech in the digital age, the 6 January attack on the United States capitol, how she survived the genocide, and how she explained what happened to her daughter.
