In the UK, protesters shouting for supporting Floyd first gathered in Trafalgar Square, chanting “No justice, no peace”. What appeared to be many thousands then made their way through Whitehall past Downing Street and the Houses of Parliament, then over the Thames to the enormous and moated US embassy at Nine Elms in Battersea.

Defying the ban on mass public gatherings because of the coronavirus lockdown, the demonstrators held cardboard placards reading Justice for George Floyd, Black Lives Matter, White Silence is Compliance, and Rest in Power.

The Metropolitan police said they had made five arrests outside the US embassy, three for violations of the coronavirus lockdown guidelines, and two for assault on police. A statement from the force said: “Those arrested are aged between 17-25 years. All have been taken into police custody.”

In updates late on Sunday, the Met said a total of 23 people had been arrested during the London protests, The Guardian reported.

Traffic was brought to a standstill as protesters crossed Lambeth Bridge, many chanting “I can’t breathe” – a reference to Floyd’s desperate plea as a white Minneapolis police officer knelt on his neck.

Protesters also made their way to Grenfell Tower in west London. One marcher wrote Black Lives Matter on the memorial at the base of the tower block, as others watched on in silence before applauding as they finished.

In Cardiff, hundreds of protesters gathered peacefully by the walls of the castle, with banners including one that read: “If you are neutral in situations of injustice you have chosen the side of the oppressor.”

Mariyah Zaman, a creative writing and media graduate, tweeted that it was a short, socially distant demonstration. “Racism is not an American issue, it’s a humanitarian issue. It exists here and it is very much apparent in Wales as the speakers today recalled.”

One protester, Donna Ali, told the BBC: “If you’re silent, you’re not going to change anything. It’s something we’ve experienced for many years, whether it’s in the US or the UK.

“It’s really heartbreaking that people can’t see past the color of skin.”

In Manchester, protesters marched through the city center, chanting “Black Lives Matter”, before gathering at 1 pm in St Peter’s Square, where they knelt in tribute to Floyd.

The London protest was watched by Sally Hitchiner, an associate vicar at St Martin-in-the-Fields church on Trafalgar Square. She told PA Media: “I’m very sympathetic to the issue but also surprised to see the strength of emotion that has gathered people together.

“It’s showing there are people in the UK who care passionately about the situation in the US. Clearly they’re not following lockdown and social distancing, but I think there’s a huge amount of passion there and that’s overriding their concerns.

“It’s an issue that requires passion but at the same time there’s a huge amount of risk in what they’re doing.”

Fمoyd died Monday in Minneapolis after a police officer put his knee on Floyd’s neck for more than 8 minutes. The officer, Derrick Chauvin, was arrested on Friday and charged with third-degree murder. Floyd was black. Chauvin is white.

The arrest has done little to quell protests across the country over the weekend. Most have been peaceful, but some have erupted in violence.

An AP tally of arrests found at least 1,383 people have been arrested since Thursday. The actual number is likely higher as protests continue Saturday night.

More than a third of the arrests, 533, came from Los Angeles alone on Friday. The mayor of the nation’s second-largest city has imposed a citywide curfew until 5:30 a.m. Sunday.

As emergency orders are lifted and beaches and businesses reopen, add protests to the list of concerns about a possible second wave of coronavirus outbreaks. It’s also an issue from Paris to Hong Kong, where anti-government protesters accuse police of using social distancing rules to break up their rallies.

Health experts fear that silent carriers of the virus who have no symptoms could unwittingly infect others at gatherings with people packed cheek to jowl and cheering and jeering, many without masks.

“Whether they’re fired up or not that doesn’t prevent them from getting the virus,” said Bradley Pollock, chairman of the Department of Public Health Sciences at the University of California, Davis, AP reported.

One protester said she has no choice.

“It’s not OK that in the middle of a pandemic we have to be out here risking our lives,” Spence Ingram, a black woman, said after marching with other protesters to the state Capitol in Atlanta on Friday. “But I have to protest for my life and fight for my life all the time.”

Atlanta Mayor Keisha Lance Bottoms, in her warning Saturday evening, said “there is still a pandemic in America that’s killing black and brown people at higher numbers.”

Minnesota Gov. Tim Walz said after another night of unrest in Minneapolis that many protesters wearing masks were simply trying to hide their identities and “cause confusion and take advantage of this situation.”

The protests started in Minneapolis following the death thereof George Floyd last Monday after a white officer pressed a knee into the black man’s neck.

The state’s health commissioner has warned that the protests were almost certain to fuel new cases of the virus. Minnesota reported 35 deaths on Thursday, a single-day high since the start of the outbreak, and 29 more on Friday.

“We have two crises that are sandwiched on top of one other,” Minneapolis Mayor Jacob Frey said.

The protests come at a time when many US cities are beginning to relax stay-at-home orders. When Los Angeles officials announced the reopening of stores last week, they said political protests could resume but with a cap of 100 people.

That didn’t stop several hundred people from showing up for a protest that shut down a freeway. Most wore masks, but many did not observe a buffer zone.

Even for the many protesters who have been wearing masks, those don’t guarantee protection from the coronavirus. The US Centers for Disease Control and Prevention recommends cloth masks because they can make it more difficult for infected people to spread the virus — but they are not designed to protect the person wearing the mask from getting it.

In Europe, unions in Paris flouted a ban on large gatherings Saturday at a march to protest conditions for workers in the country illegally. Police used tear gas to disperse the crowds and said they had banned the march due to the “health risks that such an event is likely to generate.”

Hong Kong police have used tear gas, pepper spray and rubber bullets to break up protests in recent weeks. A ban on gatherings of more than eight people has been extended to June 4, the day of an annual candlelight vigil to mark the Chinese military’s 1989 crackdown on pro-democracy demonstrators in Beijing’s Tiananmen Square.

More than 6 million coronavirus infections have been reported worldwide, with over 368,000 deaths and more than 2.5 million recoveries, according to the Johns Hopkins tally. The true death toll is widely believed to be significantly higher, with experts saying many victims died of the virus without ever being tested for it.

The US has been worst hit by the coronavirus outbreak, with more than 1.7 million cases and over 103,000 deaths, according to the tally.

In South America, the city of Bogota, Colombia, will lock down an area of nearly 1.5 million people where cases are continuing to rise.

Mayor Claudia Lopez said Saturday that no one in the working-class Kennedy area — inaugurated by late US President John F. Kennedy in 1961 — will be allowed out, except to seek food or medical care or in case of an emergency. Factories that had been allowed to operate will be ordered closed.

The area has reported more nearly 2,500 cases and hospitals are reaching maximum capacity.

Elite sporting events will be allowed to resume in England starting Monday, but without spectators, paving the way for the planned June 17 return of the Premier League, the world’s richest soccer competition.

England’s deputy chief medical officer Jonathan Van-Tam warned that the situation overall remained precarious. “I believe this is also a very dangerous moment,” he said. “We have to get this right.”
