HOUSTON – Thousands of people across the world are marking May Day, also known as International Workers' Day.
From Paris to the Philippines, people marched for workers' rights.
However, in Paris, the rallies turned violent. Several protesters and at least one police officer were hurt.
Some marchers threw Molotov cocktails at security forces, who fired back with tear gas.
Hundreds participated in a May Day march to Houston's City Hall on Monday.
March organizers said the march was aimed at protesting an agenda against workers and immigrants.
