Releasing issue is supposed to be discussed at the U.N.
At the United Nations the case of Nadiya Savchenko is on the agenda for the 60th session of the Women's Rights Committee.
The Ukrainian pilot, who is considered a political prisoner in her home country, is being held in Russia accused of accessory to murder. She faces more than 20 years in prison. The court is expected to announce its verdict next week.
Calls for the 34-year-old to be released are being heard across the world. Poland's Foreign Minister states the E.U. could tie its diplomatic relations with Russia to the question of Savchenko's fate.
Czech diplomats meanwhile insist anyone involved in the Ukrainian pilot's kidnap in eastern Ukraine in the summer of 2014 must be added to the sanctions list.
