Riot police clash with May Day protesters in Istanbul's Sarachane neighbourhood, with tens of thousands of officers deployed across the city to clamp down on similar gatherings. Istanbul's central Taksim Square was closed to rallies after 2013 demonstrations against President Recep Tayyip Erdogan's government, a move that was ruled a violation of rights by Turkey's top constitutional court in 2023. Protesters and a number of opposition politicians have called for the square to be reopened to labour rallies. IMAGES
