She had been in Russia for a court hearing for her sister’s case.
Her passport was confiscated but has now been returned.

Ukraine has convicted two Russian soldiers of supporting separatist fighters.

Vira Savchenko was told she was on the Russian federal wanted list, according to her lawyer Mark Feygin.
A criminal case has been opened against her after she allegedly insulted a judge in Grozny, the capital of Chechnya, he added
