Leaders of the Group of Seven economies told Russia on Tuesday to stop its work on a referendum in Ukraine's Crimea region and "cease all efforts to change the status of Crimea" or face action. "In addition to its impact on the unity, sovereignty and territorial integrity of Ukraine, the annexation of Crimea could have grave implications for the legal order that protects the unity and sovereignty of all states," the G7 leaders said in a statement released by the White House.
ANKARA (Reuters) - Turkish police fired tear gas and water cannon to disperse a crowd of several thousand demonstrators in Ankara's central Kizilay square on Wednesday in a protest triggered by the death of a teenager wounded in street clashes last summer. Tens of thousands of mourners, many chanting anti-government slogans, were meanwhile marching in central Istanbul at the funeral of the 15-year-old boy, Berkin Elvan, who died on Tuesday after spending nine months in a coma.
