Austrian Chancellor Sebastian Kurz has thanked Armenian Prime Minister Nikol Pashinyan for his solidarity and support in the wake of shooting in Vienna that left four civilians killed.

"This means a lot to us in these difficult times. Austria will not be intimidated by such horrific acts of terror. Together we will defend our open societies and democratic values," Kurz wrote in response to a tweet from Pashinyan.

The Armenian PM wrote earlier that Nagorno-Karabakh has been fighting against the Azerbaijani-Turkish terrorist tandem for over a month now. He said he shares the grief of the people of Austria, wishing patience to the families of the victims, and a speedy recovery to those injured in the assaults.

At least four civilians and one attacker were killed and at least 17 injured in a multiple gun attack in the Austrian capital of Vienna on Monday, November 2 night. One of the gunmen is on the run after the rampage.
