The newspaper Le Figaro quoted one teacher in a heavily Muslim neighborhood in the eastern city of Strasbourg as saying that 80 percent of her students did not participate.

At the Pierre de Geyter Middle School in St. Denis, a largely Muslim suburb north of Paris, Iannis Roder has taught history for the last 15 years. He says the day after the killings at the Charlie Hebdo magazine, the school staff knew they would have problems.

“Our pupils – a minority – didn’t want to do the minute of silence because they thought that Charlie Hebdo was a newspaper that didn’t have the right to make these caricatures,” says Roder.
