Facebook says it blocked more accounts during the US midterm elections after shutting down 115 suspected of connections to foreign efforts to interfere in the vote.

The social media giant said it blocked an unspecified number of accounts on Tuesday evening after a website that claimed to be associated with the Russia-based Internet Research Agency published a list of Instagram accounts it says it created.

Facebook said it had already blocked most of those accounts and has now blocked the rest.

A day earlier, the company had suspended 30 Facebook accounts and 85 Instagram accounts after a law enforcement tip-off they may have been linked to foreign entities.

US tech companies have stepped up efforts to fight disinformation campaigns by Russian groups, who authorities accuse of swaying the 2016 presidential election.
