We began this process with Savchenko, but fortunately, the negotiations took place at the diplomatic level and the president was also involved. The issue was resolved quickly because Russia has a selective approach when it comes to deciding what rules it should adhere to," she stated.

"The process is underway, so we hope these people will be extradited shortly. We can only hope for continued negotiations at this time, as we work out the political and legal aspects of the extradition rather than focusing on whether these people should have to return to serve out their sentence," Sevostianova added.
