Workers and activists around the world are marking May Day with largely peaceful rallies against rising prices and calling for greater rights. Pro-Palestinian sentiments are also on display. Police in Istanbul fired rubber bullets to disperse thousands of people who tried to reach the main Taksim square in defiance of a ban. In Paris, some workers set makeshift Olympic rings on fire. In South Korea's capital, thousands of protesters expressed frustration with the government. In Lebanon, people sought the end to a miserable economic crisis. “Tax the rich,” one banner in Germany read. “I want to live, not survive,” read one in France.
