The United States and Germany have voiced serious concerns about a second guilty verdict against the jailed Russian former oil tycoon Mikhail Khodorkovsky. Khodorkovsky, once Russia's richest man and considered a political threat to the Prime Minister Vladimir Putin, was convicted at a new Moscow trial of embezzlement. The White House said it is deeply concerned by the verdict calling it a selective application of justice. The German Foreign Minister Guido Westerwelle said the trial is a step back.The judge said Khodorkovsky and his business partner Platon Lebedev are guilty of stealing from their firm Yukos and laundering the proceeds. Delivering the full verdict and sentence is expected to take several days.Khodorkovsky is currently serving an eight-year sentence for fraud and tax evasion from his 2005 trial.
