Meta should do more to address the "proliferation" of fake content made with artificial intelligence (AI) tools on its platforms, the social media giant's own advisors have said.

The 21-person Oversight Board raised the concerns as it rebuked the company for leaving up an AI-generated video that claimed to show extensive damage in Haifa, Israel by Iranian forces without a label.

It called on the company to overhaul its AI rules, warning that an increase in fake AI videos related to global military conflicts had "challenged the public's ability to distinguish fabrication from fact ... risking a general distrust of all information."

Meta said it would label the video at issue within seven days.

Meta launched the oversight board in 2020 as a semi-independent group providing supervision of content moderation decisions across its platforms, which include Facebook, Instagram and WhatsApp.
