Thousands have marched in cities around the world for a second week of rallies to support the US Black Lives Matter movement, but also to highlight problems in their own countries.
There were rallies in cities across Europe, with thousands demonstrating across France, with clashes breaking out in Paris and the southeast city of Lyon.
Police arrested several far-right demonstrators gathered in London to counter an anti-racism march following violence there.
This was the second weekend of international rallies as people took to the streets to back US protests over the killing in May of black American George Floyd by a white police officer.
At the end the rally in Paris, police stopped people from launching a march through the streets of the capital, firing tear gas after some protesters pelted them with projectiles.
In the southeast city of Lyon, police used water cannons and tear gas at the end of a demonstration attended by about 2,000 people.
The Paris demonstration was called by a pressure group campaigning for justice for Adama Traore, a young black man who died in police custody in 2016.

Traore's sister Assa Traore, one of the driving forces of the group, called on those attending the rally to "denounce the denial of justice, denounce social, racial, police violence".
She drew a direct parallel between Floyd's death in the United States and that of her brother and renewed her call for a full investigation into what had happened.
Amnesty International called in a statement for "a systemic reform of police practices" in France.
The rallies came at the end of week when France's police watchdog revealed it had received almost 1,500 complaints against officers last year - half of them for alleged violence.

Clashes in London
In London, far-right protesters clashed with police in the city centre after gathering to counter an anti-racism march.
Thousands of people defied the rules to assemble in and around Parliament Square, requiring a "major" policing operation the Metropolitan Police Service.
Footage on television news channels showed some agitators throwing punches, bottles and smoke bombs at officers as well as fighting with rival protesters.
Prime Minister Boris Johnson condemned the violence, saying "racist thuggery has no place on our streets" and "anyone attacking our police will be met with the full force of the law."
Fights broke out between groups outside Waterloo station on Saturday, with fireworks thrown before police cordoned off areas. On a nearby bridge, stones were lobbed at police. Sporadic skirmishes continued in parts of the city centre.
Earlier in the day, small bands of protesters jostled and tossed bottles and cans in Trafalgar Square. Far-right groups shouted racial slurs at the anti-racism protesters, and some tried to use metal crash barriers to break through police lines.
Police said they arrested more than 100 people for offences including violent disorder and assault on police, and that six officers had suffered minor injuries. The ambulance service said it had treated 15 people.
"It is clear that far-right groups are causing violence and disorder in central London, I urge people to stay away," Mayor Sadiq Khan said on Twitter. He later tweeted millions of Londoners would have been "disgusted by shameful scenes of violence displayed by right-wing extremists".
In a brief respite to the animosity after the clashes near Waterloo, pictures showed a man identified by the crowd as a far-right protester being carried to safety by a Black Lives Matter protester.
In London the demonstrators numbered fewer on Saturday than in recent days, after announcements by far-right groups that they would converge on the city centre prompted anti-racism activists to cancel a planned march and instead call for scattered protests.
Statues of historical figures including Winston Churchill were boarded up to prevent them from becoming flashpoints or being defaced by protesters who say such monuments celebrate racists.

In and around Parliament Square, hundreds of people wearing football shirts, describing themselves as patriots and chanting "England, England" gathered alongside military veterans to guard the Cenotaph war memorial.
The far-right groups said they wanted to defend British culture, in particular historical monuments, after the toppling of the statue of a 17th century slave trader in the port city of Bristol during an anti-racism protest last weekend sparked calls for others to come down.
"Winston Churchill, he's one of our own," they also chanted, near the statue of the World War Two leader, which last weekend was sprayed with graffiti reading: "Churchill was a racist".

Thousands marched in several cities across Switzerland, with the largest in Zurich, where 10,000 people turned out. Police said one officer was hurt after a few hundred hard-left activists there began throwing projectiles. They made several arrests.
Earlier in the week, around 10,000 marched against racism in Geneva.
In Germany, around 2,000 rallied in the southern city of Stuttgart, the DPA news agency reported. In the north, another 500 turned out in Lubeck and 250 in Hamburg. There were no reports of any trouble.

Rallies in Australia
In Australia, thousands turned out in several cities for the second weekend running, despite official warnings that demonstrations would undermine the country's success in suppressing the coronavirus. The biggest was in Perth. Many demonstrators carried signs such as "Stop deaths in custody" and "White Australia stop lying to yourselves", highlighting the deaths of more than 400 Indigenous people in custody over the last three decades.
Smaller protests for Aboriginal rights were held in Darwin and towns in Queensland - both regions with numerous Indigenous communities.
In Asia, hundreds gathered in a Taipei park with some holding signs with slogans such as "This is a movement, not a moment". They held eight minutes of silence to remember Floyd.
Dozens also marched through the rain in Tokyo.
