MOSCOW -- A Russian court on Tuesday sentenced a Ukrainian pilot to 22 years in prison after convicting her for complicity to murder in the 2014 deaths of two Russian journalists in eastern Ukraine, opening a door to a possible prisoner swap between the two countries.

Ukraine President Petro Poroshenko quickly offered to exchange to Russians held in his country for the return of the pilot, 34-year old Nadezhda Savchenko.

Upon hearing the guilty verdict, Savchenko burst into song and started to chant "Glory to Ukraine!" which was echoed by Ukrainian spectators in the court room.
