Austrian authorities intend to find out who is behind the clashes between Turkish and Kurdish groups in Vienna, Austria's minister of the interior Karl Nehammer noted. 

Meanwhile, the country's MFA summoned the Turkish ambassador, Reuters reported.

“Foreign Minister Alexander Schallenberg expressed to the Turkish ambassador the clear expectation that he contribute to de-escalation rather than pouring fuel on the fire,” Austria’s Foreign Ministry said after summoning the ambassador.

“Describing demonstrators as supporters of terror organisations is something we reject. The minister urgently requested that such statements be avoided in future,” Austria’s MFA noted defending the right to peaceful protest.
