George Floyd death: US protesters defy curfews as European protests continue
Thousands defied US curfews to protest the death of George Floyd while outrage continued to reverberate in Europe on Tuesday.
Protests against racism have spread to even more US cities, becoming violent in many of them.
What began as demonstrations over the death of George Floyd after being arrested, has reawoken national outrage over deaths blamed on the police.
Al Jazeera's Mike Hanna reports. Violence has erupted in cities across the US on the sixth night of protests sparked by the death in police custody of African-American George Floyd.
Curfews have been imposed in nearly 40 cities, but people have largely ignored them, leading to tense stand-offs.
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.
The National Guard - the US reserve military force for domestic emergencies - said on Sunday that 5,000 of its personnel had been activated in 15 states and Washington, DC, where crowds once again gathered near the White House, this time lighting fires and throwing stones at riot officers.
"State and local law enforcement agencies remain responsible for security," the National Guard added.
Police in Washington DC have fired tear gas at demonstrators who set fire to properties near the White House. They include a historic church, St John's Episcopal Church, known as the church of the presidents, near the White House. Minneapolis is in the middle of a third night of unrest in the aftermath of George Floyd's death, with protesters apparently taking over the police department's Third Precinct building late Thursday. CBS Minnesota has the latest. Security measures have been eased in several American cities as unrest over the killing of George Floyd subsided.
