A lawyer for a jailed Ukrainian pilot says his client has been given forms to complete for extradition from Russia.

Nadezhda Savchenko, who was captured by Russia-backed rebels in eastern Ukraine in 2014, was sentenced to 22 years in prison last month for her alleged role in the deaths of two Russian journalists. The extradition procedure implies that she should continue serving her sentence in Ukraine, but that is unlikely because as an elected member of Ukraine's parliament she is immune from prosecution.

Savchenko's lawyer Mark Feygin told reporters in Kiev that Savchenko has been given extradition documents to complete, but he believes her transfer is still weeks away.

Savchenko is likely to be exchanged for two Russian servicemen captured in Ukraine and convicted of waging a war of aggression.
