KIEV, Ukraine - The daughter of former Ukrainian Prime Minister Yulia Tymoshenko has complained about the medical treatment her mother is receiving in prison.

Tymoshenko is serving a 7-year sentence on charges of abuse of office in a case the West has condemned as politically motivated.

Tymoshenko has been bedridden for weeks at a prison in eastern Ukraine, complaining of severe back pain and accusing authorities of denying her proper medical care.

Yevhenia Tymoshenko said on the inmate's website Thursday that she fears for her mother's life, saying medicine she has been given could be harmful.

Tymoshenko says her mother was unconscious for two hours last week after taking an unknown medicine for a cold.

Prison authorities said she merely felt dizzy after taking a shower.
