KIEV - A Ukrainian court on Monday released arrested former Georgian president Mikheil Saakashvili, who vowed to “pressure the authorities” to end corruption. Ukrainian prosecutors had sought house arrest for Saakashvili, who is accused of trying to stage a coup sponsored by Russia. But judge Larysa Tsokol ruled not to grant this request, letting the opposition politician go free for the duration of the probe, a decision met with applause from supporters in the courtroom and Saakashvili, who called the judge “courageous.”
