Zelensky joined the morning session in the lower house by video link as he seeks to drum up support for a Ukrainian military offensive.
Legislators of the right-wing FPOe left the chamber shortly after the Ukrainian leader started speaking. The session was broadcast live.
FPOe leader Herbert Kickl told reporters that Zelensky’s address ran counter to Austria’s neutrality principle. A protest was staged outside the parliament building ahead of the speech to demand that neutrality be upheld.
Zelensky has routinely addressed national parliaments abroad to give his take on the conflict. Of the 27 EU member states, only Bulgaria and Hungary have not offered him the floor.
