French and Turkish police fired tear gas at protesters as tensions erupted in both countries during May Day rallies Sunday, while thousands marched across the globe for the annual celebration of worker's rights. From Moscow to Madrid, workers chanted demands for higher wages, better conditions and more job security as many countries battle economic uncertainty and high unemployment. Police estimated some 17,000 protesters marched throughout the French capital for a rally riding a wave of anger against planned labour reforms set to come before parliament on Tuesday.
