Yulia Tymoshenko 'transferred to Ukraine hospital'.

Former Ukrainian Prime Minister Yulia Tymoshenko has agreed to end her nearly three-week hunger strike and receive medical treatment, her spokeswoman said Tuesday, CNN reported.

Tymoshenko, who has been on hunger strike since April 20, will be transferred to a hospital in the eastern city of Kharkov by Wednesday, according to spokeswoman Marina Soroka.

Tymoshenko is serving a seven-year prison sentence after she was convicted last year of abuse of authority. She went on hunger strike last month to draw attention to "violence and lack of rights" in her country after she said she was beaten unconscious in prison.

The prosecutor said his office investigated her claim of abuse and found no proof to substantiate her allegations, but European Union foreign policy chief Catherine Ashton said last month that the Ukrainian Ombudsperson's Office confirmed the report.

Ashton called on Ukraine "to examine promptly and impartially any complaints of torture or other forms of cruel, inhuman or degrading treatment."

U.S. Secretary of State Hillary Clinton also expressed concern over Tymoshenko's treatment, saying in a statement last week that photos released by the Ombudsperson's Office "further call into question the conditions of her confinement."
