A knife-wielding man who attacked a soldier guarding the Iranian envoy's residence in Vienna late Sunday was later shot dead, police said on Monday.
The motive for the attack is not yet known.
"The assailant was around 26 years old apparently an Austrian national", the spokesperson said, adding there is still no information on his identity or motives.
Police have ordered reinforcements around all diplomatic missions in the Austrian capital, which is also home to many global organisations. "The soldier defended himself well and was then able to reach for his service weapon and fire shots", he added.
Austrian police spokesman Harald Moeser said that the assailant "died on the spot" after the guard shot him four times, after pepper spray failed to stop him. The soldier was taken to hospital with a stab wound to his upper arm. They've sent additional security personnel to other diplomatic buildings across Vienna.
In the Austrian capital last week, four people were injured in knifeattacks, DPA recalls. A 23-year-old Afghan man later confessed to those attacks. You can sign up to receive it directly here.
