A video has emerged online purporting to show a gunman firing at a helpless crowd of teenagers after leaving a MacDonald's restaurant in Munich. The first video reporting to show the shootings was recorded and published to social media in the minutes after the attacks, although unconfirmed the video is being used on most mainstream media outlets.

It shows a tall man, believed to be in his twenties, in a black T-shirt leaving the fast food restaurant and firing on members of the public as they flee for their lives. The footage seems to show children and an elderly person amongst the people being targeted by the gunman.

According to the Mail Online, terrified shoppers were seen running for their lives from the Munich Olympia Shopping Centre, in the district of Moosach, after hearing gunshots.

Witnesses said that the gunman screamed "I'm German" and "f*** foreigners" before unleashing a hail of 17 bullets.

The Mail Online also claims to have viewed another video on social media in which a member of the public can be heard yelling at the suspect in the car park that he is a "w*****' and an 'a******e." And he yelled: "Put your gun down."

The gunman, when he walks across the roof of the carpark, shouts out: "I am a German!"

The man who is verbally abusing him then shouts out; "You are a w*****!" The gunman tells him to 'shut your trap.' Then he fires more shots and the rest of what is said is unintelligible.

Police in Munich believe that this was the start of the attacks and described the incident as a "shooting rampage" at Munich's largest shopping centre - Olympia-Einkaufszentrum mall. Another attack is said to have taken place at a metro station in the city with "multiple people" have been injured and killed in the attacks.

Estimates put the death toll of anywhere between six and 15 people with the injured almost certainly in double figures. A police spokeswoman said that one shooter is involved in the attack at and that no one has been taken into custody yet.

The second shooting is said to have taken place at the Stachus metro station in the city centre about five miles away from the mall. Munich's main railway station was evacuated and the entire transport network in Munich has been suspended.

Investigators believe the shootings are part of a terror attack and cite witnesses claiming to have seen three different gunman with a German official adding: "We believe we are dealing with a shooting rampage".

The shopping centre attack began inside a McDonald's restaurant shortly before 6pm (5PM GMT). There has been no official details as to the motive or suspects in the attack. The UK Foreign Office has urged Britons to avoid the areas affected and follow instructions from local authorities.

This latest shooting is the second attack in Germany in less than a week. On Monday 18 July, a 17-year-old Afghan immigrant wounded four people with an axe and knife attack on a train near the Bavarian city of Wuerzberg, around 150 miles north.
