Facebook is introducing new tools in Germany to help combat the spread of fabricated news stories.
The stories will then be passed to third-party fact-checkers and if found to be unreliable, will be marked in users' news feeds as "disputed".
It is the first major expansion of the fake news features since Facebook announced tests in the US in December.
"Last month we announced measures to tackle the challenge of fake news on Facebook," the company said on Sunday in a German-language statement.
"We will put these updates in place in Germany in the coming weeks."
