The parent company of Facebook says it is 'taking a number of steps' across its platforms to address the invasion of Ukraine.
It comes as a number of Ukrainians protested earlier outside Meta headquarters in Dublin, calling for Russian state-backed accounts to be removed.
The crowd want the owners of Facebook and Instagram to take down any profiles spreading misinformation about the invasion.
Meta says it has begun to demote posts that contain links to Russian state-controlled media websites on Facebook globally.
While over the next few days, it says it will "label these links and provide more information to people before they share them or click on them" - to let them know that they lead to state-controlled media websites.
Similar measures are also planned for Instagram.
On Monday, Meta confirmed it was blocking access to RT and Sputnik - Russian state controlled media outlets - across the EU.
This follows a move by the European Union to block access to these outlets across the bloc.
And on Sunday, Meta said it was blocking access to several accounts in Ukraine - including those belonging to some Russian state media organisations.
In a statement Nick Clegg, president of global affairs at Meta, says: "Given the exceptional nature of the current situation we are blocking access to Russian state controlled media in Ukraine and across the EU.
"Globally, we are demoting content from Facebook pages and Instagram accounts from Russian state-controlled media outlets, and we are making them harder to find across our platforms.
"We will continue to work closely with Governments on this issue."
