The Turkish Prime Minister Recep Tayyip Erdogan has again condemned the demonstrators, who staged the third day of protests, calling them anti-democratic. Crowds again converged on Taksim Square in Istanbul and there were clashes in Ankara. Mr Erdogan said protesters weremarginal groups and dismissed criticism that his government is autocratic and too Islamist.Turkey has a big economy and huge economic potential. During this government's rule, the Turkish economy stepped forward, but today we see some circles, some marginal groups who have international roots and support protest in Taksim Square and Besiktas area against the government by using the wrong arguments.
