Lawyers for a Ukrainian pilot on trial in Russia as an accessory to murder say they expect her to be found guilty and that she has asked the court to follow the sentence sought by prosecutors.

Nadezhda Savchenko is asking for the 23 years called for because if the court imposes a lighter sentence, authorities could appeal it, lawyer Ilya Novikov was quoted as saying Wednesday by the Tass news agency.

Final arguments in the case began Tuesday.

Savchenko was fighting in a volunteer battalion against Russia-backed separatists in eastern Ukraine when she was captured in June 2014.

Russian authorities say Savchenko provided the Ukrainian army with coordinates for an attack that killed two journalists and several civilians.
