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. 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. The May Day rally was the second protest against the reforms in a week to descend into violence led by troublemakers known as "casseurs" (breakers) who actively seek confrontation with security forces.
