Stampedes during three Christmas charity events across Nigeria have left at least 67 people dead in the past week, many of them children. Families are struggling during the country's worst cost-of-living crisis in a generation.

At least 32 people were killed in crowd crushes at two separate charity events in Nigeria on Saturday, police have reported.

In the third such incident this week, at least 22 people were killed in a rush for free food at a charity event.
