African American George Floyd has been buried in his hometown of Houston.

He is going to change the world, according to his brother.

It is hoped his story will become a turning point in the fight against racism - and that is not just in the United States.

Rallies over racial oppression and police brutality are spanning continents: from the United Kingdom to Senegal, tens of thousands of people are kneeling, or chanting - "I can't breathe."

The gestures represent the moments a white police officer knelt on Floyd's neck.

So, how challenging is it to combat racism around the globe?
