MINNESOTA, United States - Cities have been set on fire as protests rage across the United States following the death of George Floyd in the Minnesota city of Minneapolis.
Protesters are demanding justice after a white police officer was seen in video footage using his knee to pin the unarmed 46-year-old black man's neck to the streets.
Policeman Derek Chauvin, who was dismissed from the police department
 with three fellow officers the day after the fatal encounter,
 has been arrested on third-degree murder and manslaughter charges over the incident.
Today it has emerged a policeman has been shot dead and a second wounded amid protests in Oakland, California.
The footage has unleashed violent protests across the States, as the incident reignites barely simmering tensions over racial bias in the criminal justice system and police brutality in America.
The protests come amid years of 'Black Lives Matter' activism, following decades of pushing for change by America's civil rights movement.(FA)
