Turkish riot police have fired tear gas and rubber bullets at hundreds of anti-government protesters in Istanbul, injuring at least 10 people, including three journalists.
Dozens were arrested on Saturday in fresh protests which broke out near Taksim square, the epicentre of the violent demonstrations that disrupted the country in June.
Some 300 protesters gathered early in the evening in support of the Gezi protest movement.
"Together against fascism" the protesters shouted amid heavy security. Protest flashpoints Taksim square and Gezi park were closed to the public on Saturday.
The demonstration follows another violent protest on Wednesday night in a resurgence of the anti-government rallies which swept Turkey in June.
The original unrest was sparked by plans to redevelop Gezi Park, which is adjacent to Taksim square, but soon evolved into a broader movement against the government, seen as increasingly authoritarian.
According to police estimates, some 2.5 million people took to the streets in nearly 80 cities for three weeks to demand Prime Minister Recep Tayyip Erdogan's resignation.
Five people were killed and more than 8,000 injured in the civil unrest.
The authorities had closed the park to the public after police evicted protesters on June 15. It was reopened earlier this month but demonstrators remain banned.
