Odnovol was arrested in April when she crossed into Ukrainian-controlled territory from Crimea, which had been seized and illegally annexed by Russia in 2014.

Ukrainian Prosecutor-General Yuriy Lutsenko said Odnovol had played an active role in Russian President Vladimir Putin's election campaign by collecting signatures in 2017 from his supporters in "Russia-occupied Ukrainian territory."

Ukrainian authorities said earlier that Odnovol used her Ukrainian passport to enter Ukraine's Kherson region from Crimea.
