KIEV (AFP) - A Ukrainian court on Monday rejected requests to release detained opposition leader Yulia Tymoshenko despite global concern, as the former prime minister defiantly proclaimed her trial was run by the mafia. Judge Rodion Kireyev threw out three motions to reverse Friday's order to place Tymoshenko under arrest, including requests backed by the head of the Ukrainian Orthodox Church and 2004 Eurovision Song Contest winner Ruslana. The trial has raised alarm in the West about the rule of law in Ukraine under President Viktor Yanukovych, who defeated Tymoshenko and other leaders of the 2004 Orange Revolution uprising in presidential elections last year.
