Georgian police used pepper spray and water cannon to force protesters away from the presidential palace in the capital Tbilisi on Saturday, amid a large demonstration on the day of municipal elections, a Reuters witness said. A group of protesters attempted to force entry to the presidential palace, after some opposition figures called for a "peaceful revolution" against the incumbent Georgian Dream party, which they accuse of being pro-Russian and authoritarian. The country's pro-Western opposition has been staging protests since last year, when Georgian Dream won an election that its critics say was fraudulent.
