A disturbing live stream of what is believed to be the Christchurch mosque shooting has emerged online.

Posted on YouTube by a user who joined the platform in 2011 but has only uploaded the one video, the stream shows a gunman getting into his car, driving to a mosque and opening fire on scores of people inside.

It is believed to have originated from the Facebook page of an Australian-born man.

Photographs on the man’s Twitter page, which has since been taken down by the platform, show weapons which match the ones used in the video, scrawled with the names of infamous mass shooters

The gunman begins the video by saying “let’s get this party started” and listens to American civil war music on his way to the shooting.

Carrying a number of automatic rifles, two jerry cans and a bag with a ‘PROUDLY KIWI AS’ logo, the gunman stops his car near the mosque, takes a gun out of the boot, then walks into the building and opens fire.

He later shoots seemingly randomly on the street and returns to the car before heading back into the mosque again and repeating the process.

He flees the scene in his car in a relatively calm manner, laughing at times during the drive.

The scenes appear to have been filmed with a camera mounted on his chest.

It’s validity has yet to be confirmed.

The man is understood to have posted a manifesto online and taken to Twitter with anti-Muslim rants about birthrates and white genocide.

The names written on his weapons include Luca Traini, an Italian man who was sentenced to 12 years in prison for the drive-by shooting of six African migrants in February last year.

Alexandre Bissonnette is serving a life sentence for killing six people and injuring five others in a shooting at the Quebec Islamic Cultural Centre in 2017.

Sebastiano Venier was a Venetian general from the 16th Century who his army to victory over the Turks in the Battle of Lepanto.
