Ukrainian officials says German doctors will arrive in Ukraine on April 13 to examine the conditions at a hospital where jailed ex-Prime Minister Yulia Tymoshenko has been offered medical treatment.
A Foreign Ministry official said the doctors had "verbally" informed Ukraine's embassy in Germany that they are ready to examine the hospital in the city of Kharkiv.
Western doctors who examined Tymoshenko earlier this year found that she suffered debilitating pain from a slipped disk.
Tymoshenko's lawyer, Sergei Vlasov, has said Ukrainian officials offered to treat her at the hospital, which isn't specialized in spinal diseases.
Vlasov said Tymoshenko's supporters had asked German doctors to find out whether the hospital can guarantee the treatment prescribed to her.
Tymoshenko is serving a four-year sentence for alleged embezzlement as well as abuse of office, but she says she is a victim of political persecution.
He conviction has been condemned by the United States and European Union as politically motivated.
The EU has also called for Tymoshenko to receive hospital treatment outside of prison.
