Quiet but not calm in Turkey's Taksim Square

Protesters are again filing into Istanbul's Taksim Square, after a night of violent clashes with police, and they are refusing to leave the nearby Gezi Park.
Earlier on Wednesday, Turkey's Prime Minister, Recep Tayyip Erdogan, held a meeting with a small group of activists.
But the main campaign organisation - called Taksim Solidarity - says it was not invited.
The situation is proving the biggest test of Mr Erdogan's 10-year rule.
