For Nurten Karanci who attended the march, being a woman in Turkey means a “fight to live, to survive”.
Last year, a woman was attacked in Istanbul for wearing shorts on a public bus while another woman wearing the Islamic headscarf said she was kicked and insulted last month.
Despite a heavy police presence and water cannon trucks on standby, the Istanbul march took place peacefully as they walked from the popular Taksim Square to Sishane on the other end of the avenue on the European side of Istanbul.
Meanwhile in Ankara women hit tambourines and held “No” posters shouting their opposition to giving “one man” all the power.
Activist Ozlem Gul in Istanbul described the difficulty of being a woman in Turkey.
