During a meeting with students of Moscow State Institute of International Relations, Lavrov said:
"I was watching yesterday what was happening in Ukraine. You know, the Svoboda party extremists are, according to Ukraine's interior minister, responsible for these crimes, for murdering a National Guard employee and wounding dozens of civilians."
"Therefore, one cannot flirt with extremists anywhere, this concerns both Svoboda and the Right Sector," he added.
The violent clashes outside Ukraine's parliament were condemned by the Organization for Security and Co-operation in Europe (OSCE) and the US State Department.
