Ukrainian non-faction parliamentarian Nadiia Savchenko, who was placed in a Ukrainian Security Service (SBU) detention facility and who announced a hunger strike on March 23, has been transferred to the detention center's hospital for a medical checkup, her sister Vira Savchenko said.

"She has been moved to the detention facility's clinic for a checkup," Vira Savchenko said on the television channel 112. Ukraine on Thursday.

Nadiia has agreed to a medical examination, Vira said.

"Detention center employees have told me she will undergo a checkup with her own consent," she said.

Lawyers are not accompanying Nadiia to the hospital, as they are busy with other trials, she said.

Vira said that on Thursday she would again ask for permission to see her sister, adding that she had already submitted such a request.

"They promised to allow me to see her after lunch," Vira said.

On March 22, the Ukrainian Verkhovna Rada granted the prosecutor general's recommendation and gave its consent to prosecute, detain, and arrest Savchenko. The same day, law enforcement officials notified Savchenko that she was being treated as a suspect at parliament, after which they escorted her to the offices of the SBU branch for Kyiv and Kyiv region.

The recommendation that Savchenko be deprived of immunity from prosecution was made as part of criminal proceedings opened on counts of preparations to violently change or dismantle the constitutional system or for the seizure of power by a group of individuals acting in concert, preparations for assassinating a statesperson or a public figure by a group of individuals acting in concert, preparations for a terrorist attack by a group of people acting in concert, the establishment of a terrorist group, and the illegal handling of weapons, ammunition, or explosives by a group of people acting in concert.

Kyiv's Shevchenkivsky District Court ruled on March 23 to place Savchenko under arrest pending trial for 59 days, until May 20.
