A group of protestors who gathered at Taksim Square was dispersed by police using pressurized water and tear gas, Anadolu Ajansi reported.
In the intervention, some protestors were injured. Medical teams arrived on the scene and treated them.
A woman with head injury was taken to hospital. Her medical condition is critical.
Within the scope of the Taksim pedestrianization project, approved by the government in February 2012, the Gezi Park walls facing the Elmadag area were demolished by construction workers on Monday night. Shortly after, a group of protesters came to the park to prevent further uprooting of the trees and demolition of walls.
Earlier, Prime Minister Recep Tayyip Erdogan commented on the protests by saying that the government had made its decision and there would be no U-turn in this regard.
