MOSCOW (AP) — Workers and activists marked May Day on Tuesday with rallies to demand their government address labor issues.
International Workers' Day is a public holiday in many countries, though activities are restricted in some places, sometimes leading to confrontations.
A look at some of the events around the world:
Paris Mayor Anne Hidalgo has joined political figures condemning violence during May Day protests in the French capital that she blamed on "hundreds of masked individuals."
A car, a motorbike and a construction digger were among vehicles set on fire by vandals on Tuesday as dramatic plumes of smoke swirled into the air.
Others smashed up a McDonald's restaurant, which was left blackened with smoke inside. A Renault dealership and another car shop were also smashed up and vandalized.
Police say about 20,000 demonstrators took part in often angry demonstrations that authorities tried to disperse with tear gas.
Police say one demonstrator was lightly wounded.
Hundreds of demonstrators marched across the French capital as part of nationwide protests to oppose economic policies pursued by President Emmanuel Macron who plans to end some worker protections.
More than 100,000 people came out on the streets on Moscow to march in the traditional May Day parade.
Moscow's Federation of Trade Unions said about 120,000 people marched from the Red Square on the main streets of the Russian capital to mark May Day.
Over recent years, the parade became a highly orchestrated show of power by Russian authorities and the ruling United Russia party, with the demonstrators refraining from criticizing the government.
In St. Petersburg, Russia's second-largest city, however, Russians unhappy with the Kremlin's attempts to curtail internet freedom joined the official May Day demonstration.
Several hundred people braved the rainy weather and joined the column marching across St. Petersburg to protest the government's ban of popular messaging app Telegram.
About 10,000 people rallied in Moscow on Monday to protest the blocking of Telegram.
Police detained dozens of demonstrators during May Day events around Istanbul, most of them protesters who tried to march toward the city's symbolic main square in defiance of a ban.
Turkey declared Taksim Square off-limits to May Day demonstrations citing security concerns. Police blocked roads leading to the square but allowed small groups of labor union representatives to lay wreaths and flowers at monuments there.
Still, small groups of demonstrators, chanting "Long live May 1" and "Taksim cannot be off limits on May 1" tried to push their way into the square throughout the day, leading to scuffles with police. At least 45 demonstrators were detained.
Major trade unions gathered at a government-designated area in Istanbul for a large rally. At least six people were detained following scuffles with police at a security checkpoint leading to the rally ground.
Taksim holds a symbolic value for Turkey's labor movement. In 1977, 34 people were killed there during a May Day event when shots were fired into the crowd from a nearby building.
Communist Party head Raul Castro and Cuban President Miguel Diaz-Canel led a Labor Day parade on Tuesday, the first joint appearance by both leaders since Diaz-Canel was chosen to lead the island's government.
Both arrived at the Plaza de la Revolucion to commence the parade that drew hundreds of thousands of people, many of whom carried posters with the face of former President Fidel Castro.
"These are Fidel's and Raul's people, and today Diaz-Canel's people," the parade's official announcer in Havana said.
The Cuban government selected 58-year-old Diaz-Canel as the sole candidate to succeed Castro in April in a transition aimed at ensuring the continuity of the country's single-party system. It is not clear how much power the 86-year-old Castro will wield.
Both appeared together on a podium along with other leaders of the next generation including Cuban Foreign Minister Bruno Rodriguez and Vice President Mercedes Lopez Acea.
Other marches held throughout the country also featured banners alluding to Diaz-Canel, in addition to more usual ones of the Castro brothers.
Thousands of Greeks are marching through central Athens in at least three separate May Day demonstrations.
Museums were also shut while ferries remain were tied up in port and public transport operated on a reduced schedule in strikes marking labor day.
Police said at least 7,000 people were at the first demonstration in Athens, which was organized by a communist party-led union. The protesters marched by parliament and headed up a major avenue to the United States Embassy.
Another four demonstrations were planned in Greece's second largest city of Thessaloniki in the north.
Trains, the suburban railway, urban trolleys and ferries to and from the islands suspended operations for the day, while buses and the Athens metro system were operating on reduced schedules.
Thousands of Puerto Ricans are marching to protest pension cuts, school closures and slow hurricane recovery efforts as anger grows across the U.S. territory over looming austerity measures.
Tuesday's protest attracted teachers, retirees and unionized workers from both the private and public sector. Mayor of the capital Carmen Yulin Cruz was among those marching.
Concerns that the May 1 protest could grow violent forced the island's biggest mall to close for the day, along with several banks, government agencies and schools.
Puerto Rico is mired in an 11-year recession and trying to restructure some of its $72 billion public debt load as it struggles to recover from Hurricane Maria. About 30,000 power customers remain in the dark after the Category 4 storm struck on Sept. 20.
Tens of thousands of workers marched across Germany and Austria rallying for their rights in the face of globalization.
In Vienna, some 12,000 people gathered in front of city hall, some carrying banners with slogans against planned welfare cuts by the new government.
Meanwhile, around 4,000 union supporters marched on different routes through Berlin, before assembling at the German capital's landmark Brandenburg Gate.
"We have more rich and even richer people than we ever had before," said protester Aimo Tuegel in Berlin. "And, on the other hand, work and working conditions for workers continuing to get worse."
In Nuremberg, where the German Confederation of Trade Unions, or DGB, held its main event this year, some 6,500 protesters cheered as the group's leader, Reiner Hoffmann, said the unions "managed to civilize industrial capitalism some 100 years ago" and would also be able to tackle contemporary challenges like digitalization.
The DGB said that altogether some 340,000 people participated in almost 500 May Day events across Germany.
Danish labor union officials and left-leaning lawmakers started the day with traditional addresses to employees at work places throughout the Scandinavian country. Later in the day, thousands gathered in large parks around the country, despite rain, chilly temperatures and winds, to listen to May Day speeches that often criticized the center-right government.
While May Day was mainly a left-leaning event in Denmark, the right and the left flanks held speeches in Sweden and Norway.
Swedish Social Democratic Prime Minister Stefan Lofven suggested retired people should get more as he toured elderly homes while the center-right opposition rejected the idea. Parliamentary elections in Sweden are scheduled Sept. 9
In Norway, Sylvi Listhaug, a former justice minister until she resigned in March for writing a Facebook post claiming the opposition Labor Party was more interested in protecting the rights of terrorists than the Norwegian people, lashed out at its leader Jonas Gahr Store who heads Norway's largest party, for not being folksy, and warned against a weak immigration line.
More than 70 cities across Spain have held May Day marches calling for gender equality, higher salaries and pensions now that the country's economy is back on track.
The demonstration in Madrid was among the biggest, with thousands rallying behind the slogan "Time to win."
CCOO union official Unai Sordo says that "a social majority is emerging from the psychosis of the (global financial) crisis" in 2008 that hit Spain hard.
Pepe Alvarez, the secretary general of UGT, the other main union in Spain, said that meeting the demands of feminists, youths and pensioners are necessary to "redistribute wealth" in the country.
Spain's economy, the fourth-largest in the 19-country eurozone, has in recent years posted some of the fastest economic growth in Europe.
Hundreds of trade union members gathered outside the Macedonian government building in the capital on May Day to protest poor labor conditions and to call for the protection of workers' rights.

Hundreds of Greek Cypriots joined with Turkish Cypriots in May Day celebrations to demand a peace deal reunifying ethnically divided Cyprus and to protest against what they see as a burgeoning gap between rich and poor.
Left-wing trade unions, organizations and political parties from both sides of the divide gathered on Tuesday in the U.N.-controlled buffer zone cutting across the divided capital Nicosia in support of peace and workers' rights.
Celebrations featured music performances by Greek Cypriot and Turkish Cypriot bands in a moat beneath 16th-century Venetian-built walls surrounding the capital's medieval core. Some demonstrators waved an old Soviet flag and a Cuban flag emblazoned with the image of Ernesto "Che" Guevara.
Addressing a gathering outside Cyprus' finance ministry earlier, the leader of the communist-rooted AKEL party Andros Kyprianou criticized what he said has been a rollback of workers' hard-earned rights and privileges as well as high unemployment among young people.
A 2013 financial crisis forced Cyprus to accept a three-year, multibillion euro rescue deal from creditors.
Sri Lanka's government has postponed the rallies and processions that mark May Day because the weeklong celebrations of the national festival of Vesak carry on until May 2 this year.

The government has asked political parties and trade unions not to hold rallies on May 1. Some have said they will ignore the government directive and mark the day.

About 2,000 garment workers gathered at a park in Cambodia's capital, Phnom Penh, for a rally organized by a garment union coalition.

Prime Minister Hun Sun spent May Day with some 5,000 garment workers just outside Phnom Penh. He thanked the workers by announcing that each of them will receive 50,000 riel ($12.50). With a general election coming up in July, Hun Sen for the past year has been courting the large bloc of garment workers, whose unions traditionally have been strong supporters of the opposition.
