Ukraine's parliament has called on the leaders of Russia, Germany and France to help free Nadiya Savchenko, a Ukrainian air force officer who is on hunger strike in a Russian prison.
Savchenko is awaiting trial on charges of involvement in the killing of two Russian journalists during the conflict in eastern Ukraine.
Savchenko strongly denies the charges, and has started the second month of a hunger strike, according to her lawyer Mark Feygin.
After her imprisonment in Russia in July, Savchenko was elected to the Ukrainian parliament in October.
The resolution also calls on the Parliamentary Assembly of the Council of Europe to engage in efforts to free Savchenko.
In a letter publicized on January 12, Savchenko vowed to continue her fight.
"I have never been weak and never will be. My spirit cannot be crushed," Savchenko wrote.
