Footage of the horrific Christchurch mosque massacre is STILL available to watch on Facebook

Footage of the horrific terrorist killings of 51 worshippers in a Christchurch mosque is still available to view on Facebook, five months after the attack.

The clip shows white supremacist Brenton Tarrant, 28, entering the mosque on March 15 before killing Muslims indiscriminately with his automatic rifle. 

Tarrant, who is currently awaiting trial for 51 murders, 40 attempted murders, and engaging in a terrorist act, has been cited as an ‘inspiration’ by other alleged killers including those in El Paso and Oslo.

But the footage of him carrying out his atrocity can still be found on Facebook, with only a graphic content warning on it. 

This means that the social media giant’s algorithm has identified the video as violent, but moderators have not yet spotted it. 

You can view the full, distressing clip by simply clicking on the ‘uncover video’ button. 

It comes as New Zealand officials apologised for letting Tarrant send a letter to a supporter warning of a ‘great conflict’. 

The footage of Tarrant has been up for five months without being removed. 

It is believed that the video was missed by Facebook moderators because it was posted in Arabic.

Previous ISIS videos have been missed by social media platforms because they were in the language.  

The footage was discovered by Eric Feinberg of the Global Intellectual Property Enforcement Centre.

They have developed technology which allows them to detect terrorist communications in Arabic and other languages which may have been missed by social platforms. 

Mr Feinberg told the Telegraph: ‘It is the fifth month since the attack and there have been numerous incidences of this footage being found. You would have thought someone at Facebook would have got to the bottom of it, yet we are still finding them.

‘It gives me little confidence that the new law that is being talked about with Ofcom is ever going to work because it seems no-one knows how to identify this except someone like me and my technology.’ 

Facebook confirmed it had removed the video after being alerted of its presence. 

A statement said: ‘This was a horrific attack, and this content has no place on our platforms.’ 

Yesterday, it was revealed that white supremacist Tarrant was allowed to send a hand-written letter from his prison cell to a supporter.

Philip Manshaus, the suspected gunman in an assault on a mosque in Oslo, is believed to have been inspired by Tarrant 

The six-page ‘call to arms’ was posted this week on the website 4chan, a message-based bulletin which has been used for posts by white supremacists. 

The letter appears to be written in pencil on a small notepad and is addressed to ‘Alan’ in Russia. 

Much of it appears to be relatively innocuous, discussing a one-month trip Tarrant says he took to Russia in 2015. 

But the letter also warns that a ‘great conflict’ is coming and uses language that could be construed as a call to arms.

Corrections Minister Kelvin Davis said in a statement that he didn’t believe the prison system should have allowed Tarrant to send the letter.
