The Court of Appeal in Kiev decided to keep former Ukrainian Member of Parliament and former military pilot Nadia Savchenko behind bars after rejecting her appeal, on Thursday.
The decision left the previous appeal unchanged, with Savchenko's arrest being prolonged until September 7.
Her lawyer claims that the current verdict will be appealed.
Savchenko stands accused of plotting a terrorist act in parliament. According to the Prosecutor General, Savchenko planned to open fire and throw grenades at the deputies.
