Deutsch saidthat both the synagogue in Seitenstettengasse and an office building at the same address were closed at the time police said shots were fired.
The incident came just hours before Austria was set to go into a partial coronavirus lockdown.
The Austrian Ministry of the Interior has said the incident may have been a terrorist attack. One perpetrator is said to have been killed, others may be on the run, a ministry spokesperson told Heute.
