The Turkish police have fired tear gas and used water cannons to disperse thousands of anti - government demonstrators in the capital Ankara.On Sunday night, at least two people were injured in the clashes between the protesters and the police in downtown Kizilay square in Ankara. Meanwhile, Turkish Prime Minister Recep Tayyip Erdogan addressed thousands of pro-government demonstrators elsewhere in the capital, demanding an end to the 10-day anti-government protests. Erdogan said his patience was running out with the anti-government demonstrations. "We remained patient, we are still patient but there's a limit to our patience," Erdogan told Justice and Development Party (AKP) supporters. "Those who do not respect this nation's party in power will pay a price," he added. Earlier in the day, tens of thousands of protesters also held demonstrations against the government in Istanbul and the western city of Izmir. Late on Saturday, tens of thousands of Turkish protesters poured into the streets in Istanbul Ankara and Izmir. The unrest was triggered by the police violence against an environmental protest in Istanbul’s Taksim Square on May 31. The protests soon spread to dozens of cities across cities across Turkey and solidified into calls for Erdogan’s resignation. On Saturday, leader of Turkey’s opposition Nationalist Movement Party Devlet Bahceli called for early elections in order to overcome the current turmoil. Erdogan has faced international condemnation for his handling of the crisis. The Turkish police have also been criticized strongly for using excessive force against peaceful protests. Amnesty International censured the Turkish police for the tactics they used to control the protests.
