Thousands take part in protests across Turkey

Tens of thousands of people have taken to the streets in Turkey's four biggest cities and clashed with riot police firing tear gas for a third day in the fiercest anti-government demonstrations in years.
The din of car horns and residents banging pots and pans from balconies in support of the protests has been resonating across neighbourhoods in Istanbul, Turkey's largest city, and the capital, Ankara, late into the night.
