Turkey protests: Clashes rage in Turkish cities
PM Recep Tayyip Erdogan says four days of anti-government protests do not constitute a Turkish Spring.
At a news conference before a trip to Morocco, he said the protests were organised by extremists and accused the opposition of provoking "his citizens".
The protests initially targeted plans to build on a treasured Istanbul park but have spread into nationwide unrest.
Reports say there has been a first death in the unrest with a 20-year-old man dying after being hit by a taxi.
