Scuffles broke out in London as counter-demonstrators also came out to protect monuments targeted for their links to Britain's colonial history.

In Trafalgar Square, police separated two groups of about 100 people each, one chanting "Black Lives Matter," the other racial slurs.

At least one photographer was injured.
Demonstrations have been taking place around the world over the death of African American George Floyd in Minneapolis after a white policeman knelt on his neck.
