Turkish police used tear gas and water cannons to clear protestors from Istanbul's Taksim Square and Gezi Park on Saturday. Prime Minister Recep Tayyip Erdogan had issued a warning to the group earlier in the day to leave or face expulsion, saying "If it is not emptied, from now on, this country's security forces will know how to empty that place." The protesters ignored the threat, countering that none of their demands had been fulfilled. The PM has pledged to hold a vote on whether to redevelop the park where the protests started, instead of making an executive decision, but apparently it was too little, too late. Since the unrest started, there have been four deaths and around 5,000 people injured.
