Riot police use tear gas to disperse demonstrators as they try to march to the Turkish Parliament during a protest against Turkey's ruling Ak Party (AKP) government in Ankara February 26, 2014. The protest came after Prime Minister Tayyip Erdogan accused political enemies of faking a recording of a phone conversation suggesting he had warned his son to hide large sums of money as the graft inquiry erupted.
