MELBOURNE/TOKYO (Reuters) – Thousands took to the streets across Australia on Saturday, as did hundreds in Tokyo and Seoul to support U.S. protests against police brutality, while demonstrations were expected around Europe in the coming hours.

The rolling, global protests reflect rising anger over police treatment of ethnic minorities, sparked by the May 25 killing of George Floyd in Minneapolis after a police officer detaining him knelt on his neck for nearly nine minutes as fellow officers stood by.

Asia-Pacific demonstrations, however, were limited by social-distancing curbs aiming at stopping the novel coronavirus pandemic.

In the United States on Friday, prominent Democratic politicians adopted the slogans of the protests and announced reforms, as tensions remained high in major cities after days of largely peaceful protests that saw sporadic violence.

In Brisbane, police estimated 10,000 people joined a peaceful protest, wearing masks and holding “Black Lives Matter” placards. Many wrapped themselves in indigenous flags, calling for an end to police mistreatment of indigenous Australians.

In Sydney, a last-minute court decision overruled a coronavirus ban as several thousand people marched, amid a heavy police presence, chanting: “Whose lives matter? Black Lives matter.”

Rallies were also held in Melbourne, Adelaide and other Australian cities.

In Tokyo, marchers protested against what they said was police treatment of a Kurdish man who says he was stopped while driving and shoved to the ground, leaving him with bruises.

Organisers invoked the U.S. protests, saying they were also marching in support of the Black Lives Matter movement.

“I want to show that there’s racism in Japan now,” said 17-year-old high school student Wakaba, who declined to give her family name.

She and her friend, Moe, marching in their school uniforms, held a sign saying: “If you’re not angry, you’re not paying attention”.

“No justice, no peace, no racist police,” the crowd chanted.

In Seoul, dozens of South Korean activists and foreign residents gathered, some wearing black masks with “can’t breathe” in Korea, echoing George Floyd’s final words as he lay on the pavement. Others participated in an online “viral photo protest.”

“South Korea is becoming a multicultural society,” organiser Shim Ji-hoon told Reuters. “So I proposed this march to have awareness of racial discrimination and make a world of living together.”

With pandemic restrictions in Bangkok, activists were going online, asking for video and photos of people wearing black, raising their fists and holding signs, and explaining why they “stand united behind Black Lives Matter”.

The Thai protesters plan to gather on the video-meeting platform Zoom on Sunday and observe 8 minutes 46 seconds of silence – the period that George Floyd was filmed pinned under the officer’s knee.

Around Europe, which has seen an unprecedented wave of anti-racism rallies drawing tens of thousands onto the streets, weekend protests were planned in Germany, Britain, France, Spain, the Netherlands, Belgium and Hungary.

As in Seoul, Paris authorities banned demonstrations in front of the local U.S. Embassy, citing the coronavirus.

Some European demonstrators have been wearing masks and maintaining social distance, but in some places – notably Germany on Friday – large numbers marched closely together.

Banners and slogans have focused not just on George Floyd but on a string of other controversies in specific countries and mistreatment of minorities in general.
