Turkish police fired tear gas, water cannons and rubber bullets as they tried to stop protesters, some armed with fire bombs and fireworks, from reaching Istanbul’s Taksim square, the central focus of demonstrations last summer.
The government sent thousands of riot police onto the streets, blocking protesters as they tried to get to Taksim.
The Turkish prime minister, Recep Tayyip Erdogan, says that the street protests and a corruption scandal that has hit his government are nothing more than a plot by his opponents to bring him down.

The streets around Taksim are usually full of shoppers, tourists and local workers, but today they saw protesters and police engaged in running battles.
The government banned similar demonstrations last year, leading to thousands of protesters fighting with police.
Fighting also broke out in March after the funeral of teenager Berkin Elvan, who had been in a coma since being wounded in last year's protests.

Flag-waving demonstrators, some throwing improvised weapons, managed to break through police barricades at one point, only to be pushed back by the police.
Last week the prime minister said unions would be banned from marching on Taksim, saying protesters should instead gather in the suburbs of Istanbul. The unions roundly rejected that idea.
Last year’s violent protests were followed by mass demonstrations across the country last May, in one of the biggest threats to Erdogan's rule since his AK Party came to power in 2002.
