May Day demonstrators denounced low wages and called for reforms on Thursday during rallies that turned violent in Cambodia and in Turkey.

Clashes have erupted in Istanbul between May Day demonstrators and riot police as crowds tried to march to the city's iconic Taksim Square.

Hundreds of police in riot gear forced through barricades in Istanbul's central Taksim Square early Tuesday, pushing many of the protesters who had occupied the square for more than a week into a nearby park.
