Turkish riot police fired water cannon and teargas in running clashes with crowds in central Istanbul on Thursday, detaining hundreds. Dozens of people were injured.
"We in the commission deplore this disproportionate use of force on the first of May," Enlargement Commissioner Olli Rehn said, adding that the Commission expected the events to be investigated.
"We reiterated our call for the Turkish authorities to act within the European law and the practice to respect trade union rights in line with EU standards," he told a news conference with Foreign Minister Ali Babacan following a bi-annual trilateral meeting with the EU, Turkey and EU presidency.
Turkish authorities have defended what Turkish media called excessive force against protesters at the popular central Taksim square.
Earlier on Tuesday Turkish Prime Minister Tayyip Erdogan blamed trade unions for the protests, which had been banned due to intelligence reports that radical groups planned to stage violent protests.
He criticised the media for biased reporting on the events.
