KIEV, Nov. 20 - Ukraine’s jailed former prime minister Yulia Tymoshenko asked international medical organizations Friday to help examine and treat her worsening health conditions, The Associated Press reported.

Tymoshenko, who is serving a seven-year jail sentence on charges of abuse of office, says she is suffering from severe back pain and from mysterious bruises on her body. She says she doesn’t trust government-appointed doctors and accuses authorities of refusing to let independent medical experts see her.
