On July 11, a shootout between police officers and Right Sector militants in Ukraine's western Zakarpattia region left three people dead and 13 injured. Right Sector leader Dmytro Yarosh called for protests in large Ukrainian cities until the policemen who opened fire on group members in the western Ukrainian town of Mukacheve are detained and Interior Minister Arsen Avakov is dismissed.
"The actions of the Right Sector, primarily in the west of the country, signify that the country is divided into several parts," Willy Wimmer said.
Wimmer added that the position of Ukraine's current government is hard to understand and increases anger.
"There should be no illusions about the prospects for the current leadership to cope with major challenges [in the country]. The events in Ukraine are developing in a dangerous scenario, the consequences could pose a threat to the European security," he said.
Wimmer stated that the Russian-speaking population, whose rights are being infringed in Ukraine, acted correctly in expressing discontent with the current leadership of the country.
The Right Sector played an important part in the early-2014 Kiev riots that ended in a coup, bringing the current government to power.
On Monday, an opinion poll by the Kiev International Institute of Sociology revealed that 55.4 percent of Ukrainians answering the survey were not happy with the performance of the president.
