Turkish police on May 1, 2024, detained dozens of protesters attempting to tear down barricades in different districts of Istanbul after authorities banned May 1 rallies at the city's main Taksim Square. Tens of thousands of police were deployed across Istanbul, blocking even small sidestreets with metal barriers in an attempt to prevent groups of protesters from gathering.
