Violence has erupted in cities all over US, during protests sparked by the death in police custody of African-American George Floyd.

People took it to the streets for the sixth day in a row and Curfews have been imposed in nearly 40 cities.

Riot police clashed with protesters in New York, Chicago, Philadelphia and Los Angeles, firing tear gas and pepper bullets to try to disperse the crowds. Police vehicles were set on fire and shops were looted in several cities. Large-scale protests also took place in Atlanta, Boston, Miami and Oklahoma City.

The unrest initially began in Minneapolis in Minnesota but has now spread across the country, with reports of violence coming in from across major cities including Los Angeles, Chicago, New York, Houston, Philadelphia and Washington DC.

The police fired tear gas near the White House on Sunday night to dissuade protesters who had smashed the windows of prominent buildings, overturned cars and set fires.
