Twitter has identified and removed nearly 6,000 accounts that it said were part of a coordinated effort by Saudi government agencies and individuals to advance the country’s geopolitical interests.

Axar.az reports citing PBS that separately, Facebook said it removed hundreds of Facebook accounts, groups and pages linked to inauthentic behavior from two separate groups, one originating in the country of Georgia and one in Vietnam.

The latest crackdowns on state-backed social media campaigns came as tech companies step up efforts to tackle misinformation on their services ahead of next year’s U.S. presidential elections. The efforts followed revelations that Russians bankrolled thousands of fake political ads during the 2016 elections to sow dissent among Americans.

Twitter’s and Facebook’s announcements underscore the fact that misinformation concerns aren’t limited to the U.S. and Russia.
