Facebook has banned Russian state media from running ads and monetizing the platform over the Russian military operation in Ukraine, said Nathaniel Gleicher, the head of the social network's security policy, on Saturday.

"We are now prohibiting Russian state media from running ads or monetizing on our platform anywhere in the world. We also continue to apply labels to additional Russian state media. These changes have already begun rolling out and will continue into the weekend," Gleicher said in a tweet.
