BBC reporter's night in Taksim Square with Turkey protesters 10 June 2013 Last updated at 17:38 Help Riot police fired tear gas and water cannon to disperse the demonstrators in Ankara for the second night in a row. The word was coined in reaction to Mr Erdogan's comments describing the protesters as "calpucu," or "riffraff," before he left on a trip to North Africa. James Reynolds spent the night at Taksim Square and Gezi Park in Istanbul - the heart of the protests.
