Images of a white police officer kneeling on the neck of African American George Floyd, who later died, have sparked protests from Amsterdam to Nairobi, but they also expose deeper grievances among demonstrators over strained race relations in their own countries.

With violent clashes between protesters and authorities raging in the United States, anti-police-brutality activists gathered by the thousands in support of the Black Lives Matter movement in various European and African cities.

Peaceful protesters highlighted allegations of abuse of black prisoners by their jailers, social and economic inequality, and institutional racism lingering from the colonial pasts of the Netherlands, Britain and France.
