Turkey protests: Clashes continue despite PM's warning

Clashes between Turkish police and protesters have resumed in Istanbul's Taksim Square, despite a warning from PM Recep Tayyip Erdogan that he would not show "any more tolerance".

Police firing tear gas cleared the square on Tuesday morning, but protesters returned later in the day.

Istanbul's governor, Huseyin Avni Mutlu, said operations would go on night and day to clear the square.

Protests began 12 days ago over the redevelopment of nearby Gezi Park.
