MOSCOW/KIEV (Reuters) - Ukrainian military pilot Nadiya Savchenko arrived home to scenes of jubilation on Wednesday after her release by Russia in a prisoner swap and she promptly offered to fight again for Kiev in its conflict with pro-Russian separatists.

Savchenko's handover, in return for two Russian prisoners - had been demanded by the West and was cast as a humanitarian gesture by Russian President Vladimir Putin a few weeks before the European Union decides whether to extend sanctions against Russia imposed over its support of the rebels.
