Turkish police detain hundreds of people during protests in Istanbul on the occasion of Labor Day.

Unions and non-governmental organizations called for protests and marches in various parts of Istanbul, which has witnessed a wave of protests in the past few weeks in protest against the arrest of the city's mayor, Ekrem İmamoğlu, the main political rival of President Recep Tayyip Erdoğan.
The protesters tried to march towards Taksim Square in central Istanbul, where authorities have banned all protests for years.
The Istanbul governor's office announced in a statement that the police had arrested 384 people who protested without permission.
Gatherings are held in Turkey annually on Labor Day, but the police have intervened heavily in recent years to prevent them.
