Turkish police fired teargas and water cannons as anger erupts across the country following the death of a protester earlier in the day.
Demonstrators used fireworks and flashed laser beams at the police.
A 22-year-old died in the early hours of Tuesday during a demonstration in Hatay province in the south of the country.
The cause of the young man's death was in dispute, with witnesses saying he was hit in the head. Police said he fell from a rooftop.
Anti-government demonstrations have largely cooled since early July, but there have been sporadic protests in Istanbul, Ankara and Hatay.
