KIEV, Ukraine (AP) — The daughter of jailed former Ukrainian premier Yulia Tymoshenko urged Western nations Thursday to impose sanctions on officials involved in her mother’s imprisonment.

Tymoshenko, the country’s top opposition leader, is serving a seven-year prison sentence on charges of abuse of office after a trial that was condemned by the West as politically motivated and which strained Ukraine’s ties to Europe and the United States. Tymoshenko denies the charges and accuses President Viktor Yanukovych, her longtime foe, of orchestrating the trial to bar her from politics.
