Workers and activists marked May Day around the world Monday with defiant rallies and marches for better pay and working conditions.
Police detained 70 people in Istanbul as they tried to march. Garment workers in Cambodia defied a government ban to demand higher wages, and businesses in Puerto Rico were boarded up as the U.S. territory braced for a huge strike over austerity measures.
In Paris, police fired tear gas and used clubs on rowdy protesters at a march that included calls to defeat far-right presidential candidate Marine Le Pen. (AP)
