BERLIN (AP) — Higher salaries, better working conditions, maternity leave, minimum wage and an end to discrimination against temporary or foreign workers: These were among the concerns as hundreds of thousands of union members and labor activists rallied around the world to mark May Day.
The tradition of May Day marches for workers' rights began in the United States in the 1880s. It quickly spread to other countries at a time when industrialization pitted poorly paid employees who had few protections and little power against increasingly dominant factory employers and landowners.
Over the decades, the May Day protests have also become an opportunity to air general economic grievances or political demands. Here's a look at Wednesday's protests :

PROTESTS OVER HIGH SPEED TRAIN IN ITALY
Two protesters and a police officer were injured in the Italian city of Turin when police blocked a demonstration against the construction of a high-speed rail line between France and Italy, according to ANSA, an Italian news agency.
Among the protesters were members of the 5-Star Movement, a populist party that is in Italy's ruling coalition but is opposed to the tunnel. One member, Torino city councilor Damiano Carretto, said on Facebook that he was hit in the head and on the hand by a police truncheon.
The 35.7-mile (57.5-kilometer) long Turin-Lyon High-Speed Train tunnel link, known in Italy as TAV, is a key part of an EU project linking southern Spain with eastern Europe. But the 5-Star Movement has long opposed the project.

RUSSIAN WORKERS MARCH AT RED SQUARE
Authorities in Russia said about 100,000 people took part in a May Day rally in central Moscow organized by Kremlin-friendly trade unions on Red Square. Opposition activists said more than 100 people were detained in several cities, including for participating in unsanctioned political protests.
In St. Petersburg, police arrested over 60 supporters of opposition leader Alexei Navalny. Some of them carried signs saying "Putin is not immortal," in reference to Russian President Vladimir Putin, who has been at the helm since 2000.
Police manhandled dozens of protesters in Russia's second-largest city, including lawmaker Maxim Reznik, who was later released. Reznik told the Dozhd TV station that police detained almost everyone in his protest group but gave no reason for the arrests.

French police clashed with stone-throwing protesters who set fires and smashed up vehicles as thousands of people gathered for May Day rallies under tight security. About 165 arrests were made.
Police repeatedly used tear gas to try to control the crowd gathering near Paris' Montparnasse train station for the main protest. Some protesters were injured. Associated Press reporters saw groups of hooded, black-clad people shouting anti-police slogans, mixing with other protesters wearing yellow vests or waving union flags.
France's interior minister warned earlier that "radical activists" could join the protests in Paris and elsewhere, and deployed 7,400 police to counter them.

DETENTIONS AT TURKEY'S MAY DAY RALLIES
Turkish police detained May Day demonstrators trying to march toward Istanbul's main square, which has been declared off-limits by authorities, who cited security concerns. Still, small groups chanting "May Day is Taksim and it cannot be banned," attempted to break the blockade, with dozens reportedly detained. Taksim Square has held symbolic value for Turkey's labor movement since 34 people were killed there during a May Day rally in 1977 when shots were fired into the crowd from a nearby building.
