Citing a paywalled source isn't really non-credible. DN is absolutely a credible source. But for anyone that's doesn't have a DN sub, read the SVT article like someone else suggested. The Euronews article is probably good too.
But personally I would probably dismiss any newspaper with such a stupid name.
Here is the DN article for anyone that's interested (copy pasted using Firefox reader, so pardon my formatting): https://paste.ee/p/4MIBi
