Several thousands of police officers have been transported to Taksim square and Gezi park in the center of Istanbul.

The measures are taken due to the risk of uprising in connection with the anniversary of last year’s events when hundreds of demonstrators occupied Taksim square.

Turkish PM Recep Tayyip Erdogan warned citizens against holding mass protest actions, assuring that law enforcers were instructed to take measure.

Security department blocked the subway and stopped ferries between Asian and European parts of Istanbul. According to the authorities, around 25 thousand police officers have been deployed in Taksim. Fifty vehicles equipped with water cannons and a few dozen buses with special forces are on duty, ITAR-TASS reported.
