Americans awoke Sunday to charred and glass-strewn streets in dozens of cities after another night of unrest fueled by rage over the mistreatment of African Americans at the hands of police, who responded to the violence with tear gas and rubber bullets.

Tens of thousands marched peacefully to protest the death of George Floyd, a black man who died Monday after a white Minneapolis police officer pressed his knee on his neck until he stopped breathing. But many demonstrations sank into chaos as night fell: Cars and businesses were torched. The words 鈥淚 can鈥檛 breathe鈥� were spray-painted all over buildings. The damaged buildings include many near the White House.

The scale of the protests, extending to nearly every part of the country and unfolding on a single night, seemed to rival the historic demonstrations of the civil rights and Vietnam eras. And by Sunday morning, the outrage had spread to Europe, where thousands gathered in London鈥檚 Trafalgar Square. Despite government rules barring crowds because of the COVID-19 pandemic, demonstrators clapped and waved placards as they offered support to U.S. demonstrators.

鈥淲e鈥檙e sick of it. The cops are out of control,鈥� protester Olga Hall said in Washington, D.C. 鈥淭hey鈥檙e wild. There鈥檚 just been too many dead boys.鈥�

People set fire to squad cars, threw bottles at officers and busted windows of storefronts. They carried away TVs and other items even as some protesters urged them to stop. In Indianapolis, multiple shootings were reported, including one that left a person dead amid the protests, adding to deaths in Detroit and Minneapolis in recent days.

In Minneapolis, the city where the protests began, police, state troopers and National Guard members moved in soon after an 8 p.m. curfew took effect to break up the demonstrations.

President Donald Trump appeared to cheer on the tougher tactics Saturday night, commending the National Guard deployment in Minneapolis, declaring 鈥淣o games!鈥� and saying police in New York City 鈥渕ust be allowed to do their job!鈥�

Presumptive Democratic presidential nominee Joe Biden condemned the violence as he continued to express common cause with those demonstrating after Floyd鈥檚 death.

鈥淭he act of protesting should never be allowed to overshadow the reason we protest,鈥� Biden said in a late-night statement.

On Sunday, maintenance crews near the White House worked to replace windows that had been completely shattered with large pieces of wood. Buildings for blocks were marked with graffiti, including curses about Trump and anti-police sentiments. Shattered glass still covered the sidewalks. The damaged buildings included the Department of Veterans Affairs, directly across the street from the White House.

Cleanup soon began in cities across the country. In Madison, Wisconsin, hundreds of volunteers gathered to pick up after the violence that included setting a police squad car on fire, stealing from businesses and breaking windows at dozens of stores and an art museum.

Few corners of America were untouched, from protesters setting fires inside Reno鈥檚 city hall, to police launching tear gas at rock-throwing demonstrators in Fargo, North Dakota. In Salt Lake City, demonstrators flipped a police car and lit it on fire. Police said six people were arrested and an officer was injured after being struck in the head with a baseball bat.

Overnight curfews were imposed in more than a dozen major cities nationwide, including Atlanta, Denver, Los Angeles, Minneapolis, San Francisco and Seattle.

At least 13 police officers were injured in Philadelphia , and at least four police vehicles were set on fire. In New York City, dangerous confrontations flared repeatedly as officers made arrests and cleared streets. A video showed two NYPD cruisers lurching into a crowd of demonstrators who were pushing a barricade against one of them and pelting it with objects. Several people were knocked to the ground. It was unclear if anyone was hurt.

鈥淭he mistakes that are happening are not mistakes. They鈥檙e repeated violent terrorist offences, and people need to stop killing black people,鈥� Brooklyn protester Meryl Makielski said.

Georgia Gov. Brian Kemp authorized the deployment of up to 3,000 National Guard troops to Athens, Savannah and any other cities where more demonstrations were planned Sunday. Kemp had already approved up to 1,500 Guardsmen to help enforce a 9 p.m. Saturday curfew in Atlanta.

鈥淭he protesters need to know we鈥檙e going to support their efforts in a peaceful, nonviolent protest,鈥� the Republican told television station WSB late Saturday. 鈥淭he agitators need to know that we鈥檒l be there 鈥� to take them to jail if they鈥檙e destroying lives and property.鈥�

In Virginia鈥檚 capital city, graffiti invoking Floyd or directing slurs at the police dotted downtown, including many of Richmond鈥檚 some prominent Confederate monuments. At the headquarters of the United Daughters of the Confederacy, which news outlets reported was vandalized and set ablaze, a few men with long guns were among a small crowd gathered outside. One man said they were there to protect the building.

In Ferguson, Missouri, where Michael Brown Jr. was shot and killed by a white police officer in 2014, sparking a wave of protests throughout the country, six officers were hurt after being hit with rocks and fireworks.

Police have arrested nearly 1,700 people in 22 cities since Thursday, according to a tally by The Associated Press. Nearly a third of those arrests came in Los Angeles, where the governor declared a state of emergency and ordered the National Guard to back up the city鈥檚 10,000 police officers as dozens of fires burned across the city.

This week鈥檚 unrest recalled the riots in Los Angeles nearly 30 years ago after the acquittal of the white police officers who beat Rodney King, a black motorist who had led them on a high-speed chase. The protests of Floyd鈥檚 killing have gripped many more cities, but the losses in Minneapolis have yet to approach the staggering totals Los Angeles saw during five days of rioting in 1992, when more than 60 people died, 2,000-plus were injured and thousands arrested, with property damage topping $1 billion.

But not all protests were marred by violence. In Juneau, Alaska, local police joined protesters at a rally in front of a giant whale sculpture on the city鈥檚 waterfront.

鈥淲e don鈥檛 tolerate excessive use of force,鈥� Juneau Police Chief Ed Mercer told a gathering where most people wore masks and some sang Alaska Native songs.

The show of force in Minneapolis came after three days in which police largely avoided engaging protesters, and after the state poured more than 4,000 National Guard troops into Minneapolis. Authorities said that number would soon rise to nearly 11,000.

鈥淭he situation in Minneapolis is no longer in any way about the murder of George Floyd,鈥� said Gov. Tim Walz, who also said local forces had been overmatched the previous day. 鈥淚t is about attacking civil society, instilling fear and disrupting our great cities.鈥�

Some residents were glad to see the upheaval dissipating.

鈥渓 live here. I haven鈥檛 been able to sleep,鈥� said Iman Muhammad, whose neighbourhood saw multiple fires set Friday night. Muhammad said she sympathized with peaceful protests over Floyd鈥檚 death but disagreed with the violence: 鈥淲rong doesn鈥檛 answer wrong.鈥�
