Hardcore porn has been tweeted from a Welsh Office Twitter account.
An extremely graphic screenshot was shared on social media after being re-tweeted on Monday afternoon from the UK Government in Wales Twitter account.
The message was quickly deleted and a spokesman has since alleged that the account had been the victim of a "cyber-attack".
Stace Williams Tweeted: "That awkward moment when the UK Government in Wales account tweets porn into your timeline."
Another social media user posted: "Biggest faux pas of the day goes to whomever is running the UK Government in Wales @UKGovWales Twitter account who r/ted this."
Following the incident, UK Government in Wales posted on Twitter: "We are aware that our account was subject to a cyber-attack earlier.
"We apologise for any offence caused by the material shared.
"We are confident the issue has now been resolved.
