Far-right protesters and leftists around the world hit the streets for May Day - take a look at the dramatic protests
May Day, celebrated on the first day of May every year, has long been a symbolic day for workers' rights around the world.
But May Day 2018 turned out to be a day of violent clashes between police and protesters, as both left-wing and right-wing activists took to the streets with fire and fists, from Paris to Istanbul.The idea of May 1 as a day for workers' rights was born in the US city of Chicago, where on May 1, 1886 hundreds of thousands of people walked off the job to protest long hours and harsh working conditions.
Eight years later, then-president Grover Cleveland moved the original, US version of Labor Day to September, and Americans now celebrate their Monday off as more of a work vacation than a call to action.
But 66 other countries around the world still celebrate the May 1 rite of spring as International Workers' Day, with strikes for workers' rights. And in recent years, far-right groups and Neo-Nazis have also decided to use the opportunity to raise their voices.
