One of the victims of Monday's terrorist attack in Vienna has been identified as a Chinese national by China's embassy in the Austrian capital.

Li Qiang has been named as one of the four people who were killed in the shooting, which was carried out by a convicted terrorist in the heart of Vienna.

The 39-year-old had moved from southern China to Austria more than 25 years ago and owned two restaurants in the capital.

Another person of Chinese origin is believed to have been injured in the attack but hasn't yet been named.

On Tuesday, a German woman was confirmed as one of the victims by Germany's Foreign Minister Heiko Maas, who released a statement offering condolences to her family.

Maas said: "We now have the sad certainty that a German citizen was among the victims of the attack in Vienna. Our sympathies go out to her friends and loved ones."

In the aftermath of the attack, armed gunmen have surrounded the Stadttempel Jewish synagogue, outside which the attacks began, while police have marshaled cars to and from Vienna's airport.

The usually bustling streets have been quiet as Austria enters the third day of a second national lockdown to combat the spread of COVID-19. 

However, some locals have ventured out for work and revealed their sadness and anger at Monday's shocking events.

Student Zaccaria Assalmonashev told Reuters: "These people want to make Islam bigger and bigger but in fact they make it smaller and smaller. And so they destroy it."

Vienna resident Josef Neubauer added: "Something like this was to be expected, even in Vienna. It's a big city. Berlin, Paris – it was just a matter of time."
