Facebook has claimed a 'bug' caused the platform to save copies of videos that had been deleted by its users.
The social network was recently caught storing videos that users had recorded but never posted on the platform.
Facebook today apologised for the issue and promised that it would permanently delete the video content in question.
It also confirmed the deleted content was never publicly shared, although it remains unclear whether Facebook used the footage in any other way
The apology comes as Facebook battles a privacy scandal over the harvesting of personal data on 50 million users by political firm linked to Donald Trump's 2016 campaign.

A Facebook spokesperson told MailOnline: 'We investigated a report that some people were seeing their old draft videos when they accessed their information from our Download Your Information tool.
'We discovered a bug that prevented draft videos from being deleted. We are deleting them and apologise for the inconvenience.'
The company did not address how widespread the issue is and did not reveal whether there is a way to make sure videos have been removed.
The issue emerged when thousands of users began downloading their personal data from the site amid the Cambridge Analytica data scandal.
The documents includes personal call records, text messages, as well as your location each time you log into the site.

Last Wednesday, users digging into the new feature complained that the social media giant had kept hold of videos they thought they had deleted.
In the years before Snapchat, Instagram Direct and FaceTime, many people would post clips of themselves directly to the walls of their Facebook friends.
Depending on what they were posting it's possible they recorded several takes.
Many thought that those oft-embarrassing takes were history after they were deleted.
But Facebook's user data logs have revealed the company held onto those videos all along.
One Twitter user claimed that Facebook had been saving videos their friends recorded, but never posted on their wall, too.
If you've downloaded an archive of your Facebook data, the videos are relatively easy to find.
In each .zip file, Facebook categories the data into different tabs labelled under content headings like Photos, Friends and Ads, among other things.
Under the Videos tab, there are copies of any videos you might have shared on another user's timeline, as well as the ones you deleted.
To view them, you'll most likely need to download a free program called VLC Media Player, which is able to play a variety of different file formats.
Facebook maintains that it doesn't sell the data it collects, which includes phone contacts and text history, or collect the content of your text conversations or call logs
While it seems like a breach of privacy that Facebook kept these videos, according to the firm's data policies, it was well within its rights to do so.
'We collect the content and other information that you provide when you use our Services, including when you sign up for an account, create or share, and message or communicate with others,' Facebook's website reads.
Even if you deleted clips recorded on Facebook, you still created them using the website's tools, which means the firm was technically allowed to store them.
Yesterday, chief executive Mark Zuckerberg Facebook said Facebook would need 'a few years' to fix the problems uncovered by the revelations on the hijacking of private user data.
Speaking to the news site Vox, Zuckerberg defended the company's business model and shot back at criticism of the social networking giant from Apple CEO Tim Cook last week.
The chief executive also maintained that one of Facebook's problems was that it was 'idealistic,' focusing on the positive aspects of connecting people.
He said 'we didn't spend enough time investing in, or thinking through, some of the downside uses of the tools.'
Facebook shares are down 13 per cent since March 16, when it first acknowledged that user data had been improperly channeled to Cambridge Analytica.
The company has lost more than $70 billion in market value since then.
Zuckerberg himself is down more than $10 billion, taking his net worth to just above $60 billion.
