The British Army's Twitter and YouTube accounts have been hacked.
The army confirmed a “breach” of its Twitter and YouTube accounts on Sunday evening.
An investigation is under way after both official sites were hacked.
The army’s YouTube channel features videos on cryptocurrency and images of billionaire businessman Elon Musk.
The official Twitter account has retweeted a number of posts appearing to relate to non-fungible tokens (NFTs).
Watch: What are NFTs?
An NFT is a crypto asset – such as an image, video or text – which people can be certified to own via blockchain.
An army spokesperson said: “We are aware of a breach of the army’s Twitter and YouTube accounts and an investigation is under way.
“We take information security extremely seriously and are resolving the issue. Until the investigation is complete it would be inappropriate to comment further.”
The British Army's Twitter account appeared to be back to normal shortly after 8pm on Sunday.
