Ukrainian pilot and lawmaker Nadiya Savchenko has thanked Poland for its support in obtaining her release after almost two years of Russian captivity.

Savchenko, 35, attended a session of Poland's Parliament in Warsaw on Thursday and met with Deputy Parliament Speaker Ryszard Terlecki and other lawmakers.

She told reporters she wanted to thank her "Polish friends" for support, also expressed in private letters to her.

Warsaw supports Ukraine's pro-democracy forces and Poland's lawmakers and officials spoke publicly in Savchenko's defense when she was held in Russia, where she was convicted on charges of contributing to the deaths of two Russian journalists and given a 22-year prison term. She denied the charges.

She was released in May and swapped for two Russians convicted of fighting in eastern Ukraine.
