'No release' for Ukrainian prisoner
Russian investigators say there are no grounds to release a key Ukrainian prisoner despite claims by Ukraine's president that she would soon be freed.
Russia's Investigative Committee said only a court could free Nadezhda Savchenko, a Ukrainian air force officer who has been on hunger strike in a Moscow prison for more than two months.
After marathon peace talks in Minsk, Belarus, Ukrainian president Petro Poroshenko said Ms Savchenko would soon be released.
Russia has charged her with involvement in the deaths of two Russian journalists in eastern Ukraine. Moscow claims she voluntarily crossed the border into Russia before she was detained, which she denies.
The Minsk agreement calls for the exchange of all illegally held prisoners and hostages.
