Horrifying footage has emerged out of Vienna, where a suspected terror attack continues to unfold.
The video shows pedestrians ducking for cover by a bike rack on the street of the Austrian capital as a number of shots ring out.
Two distinct shots can be heard before a barrage of gunfire, then a pause, then more shots.
Viennese police have confirmed that an officer was shot during the major incident that has seen the central city put into lockdown.
Unconfirmed reports have suggested as many as seven people have died during the attack, with up to 15 being treated in hospital.
Austrian state broadcaster ORF said the police have confirmed several people are dead but the exact number is not yet known.
One person has been arrested while a second suspect is believed to have been killed by police.
Austrian Interior Minister Karl Nehammer has confirmed authorities are still hunting multiple suspects who remain at large in the city.
It’s believed the perpetrators targeted six locations within a small area of central Vienna, including three restaurants, a synagogue, a Jewish cultural centre and a Hilton hotel.
“Following reports of a security incident in Vienna, our three hotels have locked down as a precaution,” a Hilton spokesperson told Daily Star Online.
“We are in touch with all three hotels and have no current information to suggest our guests or team members at the hotel are directly involved in the incident.”
Hostages are reportedly being held at Akakiko restaurant on Mariahilfer Strauss, near the synagogue where shots were heard earlier in the evening.
A number of alarming videos have been posted to social media by terrified Viennese citizens caught up in the chaos.
One purported to show one of the alleged suspects, who was seen running across an empty street wearing a balaclava and holding a large long-barrelled firearm.
Another, filmed from an upper-storey window, seemed to show a figure falling after being shot by police.
French President Emmanuel Macron, whose own country was targeted by terrorists last week, has tweeted his support for Austria.
“After France, it is a friendly country that is under attack. This is our Europe,” he said.
“Our enemies need to know who they are dealing with. We won’t give in to anything.”
The shooting in Vienna comes just days after France was targeted in a string of Islamic terror attacks, one of which saw two people decapitated in a church in Nice.
