French riot police charge towards protesters during the traditional May Day labour union march with French unions and yellow vests protesters in Paris, France, May 1, 2019. Reuters Photographer Gonzalo Fuentes: "The May Day labour union march in Paris was joined by the Yellow Vest protestors and the Black Bloc Ð anti-globalisation anarchists who wore black clothes and covered their faces. Following several months of Yellow Vest demonstrations, the challenge was to avoid an image repeat. I walked in the march until I identified a small group of Black Bloc who were trying to blend in. Walking next to them for a while allowed me to feel those little tensions that usually precede a clash. A couple of hours later I followed a polices tactical unit on the move and decided to stay close to them which led me to a confrontation. However, the crowd suddenly moved, and I found myself standing between the police and the demonstrators at the exact moment an officer pointed a teargas canister to disperse activists. I was there with my camera pointing at him and without thinking I took the picture. Luckily the police officer never fired his teargas canister as the demonstrator was arrested. It wasn't until I saw the image in my camera that I realised that I was standing too close to the clash. As photojournalists we try to blend in with the crowd to work. But protestors do this too Ð pretending to be media by using cameras to approach the police." REUTERS/Gonzalo Fuentes/File Photo SEARCH "POY STORIES 2019" FOR THIS STORY.
