Turkish police on Friday fired tear gas and arrested hundreds of people holding May Day demonstrations in Istanbul, as thousands rallied nationwide.
According to the CHD Lawyers' Association, police had arrested at least 550 people by mid-afternoon in Istanbul, where police fired tear gas from riot-control vehicles into the crowd, AFP journalists observed.
"The number of people in police custody -- or whom their relatives suspect are in custody -- from whom we have not heard anything, stood at at least 550," by 4:00 pm (1300 GMT) said a CHD statement.
The authorities did not immediately comment on the detentions in the country's economic capital.
Images aired on the opposition channel HALK TV also showed the president of the Turkish Workers' Party, Erkan Bas, engulfed in pepper spray.
"Those in power already speak 365 days a year, so let workers talk about the hardships they face at least one day a year," he said.
Two groups were specially singled out in the city's European side after signaling their intention to march to Taksim Square -- the scene of several anti-government protests in the past -- which was sealed off overnight by police.
A union official, Basaran Aksu, was arrested just after he had denounced the Taksim lockdown.
"You can't close off a square to the workers of Türkiye. Everyone uses Taksim, for official ceremonies, for celebrations. Only the laborers, the workers, the poor find the square closed to them," he said.

May Day, which celebrates workers and the working classes, sees a major police deployment in Türkiye every year, with a large area in the heart of Istanbul around Taksim Square sealed off.
Last year, protests moved to the Kadikoy area of the city and more than 400 people were arrested.
The number of arrests this year appeared to be approaching that level.
The CHD lawyers' group, which was present at the rallies, said on a post on X that, at 1100 GMT "according to our information, the number of people in custody stands at 370".
On Friday, large numbers of police, many in riot gear, deployed, setting up metal barricades to cut off access to central neighborhoods of Istanbul.
In the Mecidiyekoy district, AFP reporters saw police use tear gas on the crowd, which included members of a Marxist party, the HKP, as they tried to push through while chanting "USA murderer, AKP (Türkiye's ruling party) accomplice".
Police encircling the Besiktas neighborhood stepped in -- sometimes violently -- whenever a chant was taken up by the demonstrators. AFP saw several protesters thrown to the ground.
Unions and civil society associations had called for the May 1 demonstrations under the slogan "Bread. Peace. Freedom".
While inflation in Türkiye is officially pegged at 30 percent, it is closer to 40, according to independent estimates.
In Ankara, about 100 coal miners who had staged a nine-day hunger strike to demand wage arrears were cheered as they joined the May Day march.
The turnout, notably large and youthful, was monitored by a significant police presence, an AFP journalist said.
Earlier this week, Turkish authorities issued arrest and search warrants against 62 people, of whom they deemed 46 -- including journalists, trade unionists and opposition figures -- "likely to carry out attacks".
