Turkey May Day protests hit by tear gas near Taksim Square

Police used water cannon and tear gas to try to disperse protesters, as Selin Girit reports

Riot police in Turkey have used tear gas and water cannon to prevent demonstrators defying a ban on protests on Istanbul's central Taksim Square.

The Anatolia news agency said several demonstrators were injured and at least five detained.
Intensive security measures were in place, and roads and streets near Taksim Square closed to traffic from the early morning.
Turkish media said some 40,000 police would be deployed in the city on 1 May.
Prime Minister Recep Tayyip Erdogan earlier warned people they should "give up hopes" of gathering on Taksim Square - a focus of anti-government protests.

Taksim Square, a traditional rallying point, was almost empty after access was restricted by Turkish police as part of May Day security measures

But a joint statement from the main trades unions on Wednesday said: "We will be in Taksim despite the irrational and illegal ban. All roads will lead to Taksim on May Day".
Mr Erdogan's party won local elections in March. That was the first vote since mass protests last June, and was seen as a barometer of his popularity.
The prime minister has been eyeing a run for the presidency in August - the first time voters will directly elect the head of state - or may seek to change the rules to allow him to seek a fourth term in office.
