As reported by Censor.NET citing Voice of America, this was said by U.S. Mission to OSCE Deputy Chief Kate Byrnes.
The Chargé d'Affaires said that observers recorded shots fired from the separatists-controlled territory on April 29 demonstrating Russia's continued behavior undermining the cessation of hostilities.
According to Byrnes, Russia's reluctance to join the rest of the countries in their support for the observers correlates with its efforts to deny the monitors access to the territories controlled by combined Russian-separatist forces.
The U.S. diplomat also called to stop persecuting journalist Mykola Semena. She stressed that the Russian aggression against Ukraine undermined foundations of Europe's security and stability and directly contradicted the idea of united, free and peaceful Europe.
As reported, the Russian invaders searching links with Krym.Realii news outlet raided a number of journalists' homes in Crimea April 19, 2016. It later came to be known that Crimean journalist, a staff writer for Radio Svoboda Mykola Semena was detained after the raids.
Semena was served indictment in the case of separatism on Jan. 20.
