As night falls in Turkey violent clashes have erupted in a fourth day of anti-government protests.

In what is now becoming a familiar sight in the capital Ankara, police fired water cannon and tear gas to disperse protesters.

They are calling for Prime Minister Recep Tayyip Erdogan to resign. He accused them of walking ‘arm in arm with terrorism’ – remarks which could further inflame anger after some of the most violent riots in decades.

The unrest shows no signs of dying down.

A two-day strike, starting Tuesday has been called by Turkey’s public sector unions to protest over the crackdown on what had begun as peaceful demonstrations.

The first death related to the unrest has been reported – a 20-year-old died when a taxi drove into a group of demonstrators.

More than 1,700 people have been arrested since the clashes began – though that figure is likely to change overnight.
