It is 25 years since one of the worst atrocities in modern history: the Rwandan genocide, in which 800,000 people, mostly from the Tutsi minority, were slaughtered. In 2016, the Rwandan Church offered an official apology for its part in the killings. Priests took part in or acquiesced in the genocide; churches, sought as refuges, became death traps.

Last month, the process of acknowledging the past continued, at the Amahoro National Stadium in Rwanda’s capital city Kigali. The new archbishop, Antoine Kambanda, was being installed; Kambanda appeared alongside President Paul Kagame.
