Ukraine expanded sanctions against Russia last month after a Russian court found Savchenko, 34, guilty of complicity in the killing of two Russian journalists and sentenced her to 22 years in prison, Reuters wrote.
Ukraine called on the European Union to follow suit, and Lithuania became the first EU state to do so. The 46 people it blacklisted are banned from entering Lithuania for 10 years.
Those blacklisted include Russian investigators, prosecutors and judges, as well as separatists from the Ukrainian rebel strongholds of Luhansk and Donetsk, Lithuanian Foreign Minister Linas Linkevicius told Reuters.
"We blacklisted them to show our solidarity with Ukraine and to focus attention on the unacceptable and cynical violations of international law and human rights in Russia. We are convinced that the court cases against those people were falsified," Linkevicius told Reuters by phone.

Regarded as a national hero by many in her homeland, Savchenko has been depicted by Russian state TV as a dangerous Ukrainian nationalist with the blood of civilians on her hands. Russia has ignored calls from the European Union and the United States to free her on humanitarian grounds.
