Meta removed an altered video falsely depicting Ukrainian President Volodymyr Zelensky ordering troops to surrender Wednesday. The video is the latest alarming milestone in the parallel information war accompanying Russia’s brutal invasion of neighboring Ukraine, but it was a moment that Ukraine’s government and social media companies appear to have been prepared for.

Meta Head of Security Policy Nathaniel Gleicher explained that the company removed the content for breaking its rules against “manipulated media,” a form of multimedia misinformation that often manifests as video edited to depict a public figure saying something that they never actually said.
