MOSCOW, October 13 (RAPSI) - Sister of Ukrainian military ex-pilot Nadezhda Savchenko who stands charged with involvement in the killing Russian journalists as well as civilians in Donbas, has been banned from entering Russia until 2020, lawyer Mark Feigin wrote on his Twitter account on Tuesday.

Under these circumstances, Vera Savchenko cannot testify upon the trial of her sister Nadezhda, Feigin said.

Nadezhda Savchenko was arrested in Russia last summer on charges of involvement in the murder of two Russian TV journalists during hostilities in Donbas and on illegally crossing the border into Russia.

TV correspondent Igor Kornelyuk and sound engineer Anton Voloshin were killed on June 17 in a mortar attack.

Savchenko, who denies all the charges, is facing 25 years in prison.

Her attorneys claim that Savchenko was framed and that there is no evidence of involvement in the journalists’ murder. They also claim she did not cross the border voluntarily but was kidnapped.
