A man is doused by a water cannon during clashes as people gather at the Bois de la Cambre/Ter Kamerenbos park for a party called "La Boum 2" in defiance of Belgium's coronavirus disease (COVID-19) social distancing measures and restrictions in Brussels, Belgium May 1, 2021. Reuters photographer Yves Herman: "To contain a rising wave of COVID-19 infections, Belgium announced in March its third lockdown since the pandemic started, closing schools and most businesses for four weeks. Bristling at the restrictions, a group on Facebook announced an unauthorised party, or "La Boum", would take place in a park in Brussels. The gathering, which attracted about 2,000 people, was in defiance of the government's limit of no more than four people together outside. The clashes between police and protesters took place in several locations in the park. The man in the photo, being doused by a police water cannon, is a former teacher who decided to take part in the gathering. He had begun to walk toward the police cordon as the water cannon was fired. The man was not seriously injured." REUTERS/Yves Herman/File Photo SEARCH "POY STORIES 2021" FOR THIS STORY.
