Meta Platforms said it was further narrowing its content moderation policy for Ukraine to limit calls for the death of heads of state, Reuters reported, citing an internal company document.

The move comes after Reuters reported last week that Meta was temporarily allowing some Facebook and Instagram posts calling for the death of Russian President Vladimir Putin or Belarusian President Alexander Lukashenko.

Following this, Meta said a temporary change to its content policy, applicable only to Ukraine, is necessary to allow users to express opposition to the Russian attack. On the same day, Russia opened a criminal case against the social network.

“We are now narrowing the focus to make it explicitly clear in the guidance that it is never to be interpreted as condoning violence against Russians in general,” Meta global affairs President Nick Clegg wrote in a post on the company’s internal platform on Sunday that was seen by Reuters.

“We also do not permit calls to assassinate a head of state...So, in order to remove any ambiguity about our stance, we are further narrowing our guidance to make explicit that we are not allowing calls for the death of a head of state on our platforms,” Clegg said.

Clegg wrote that Meta plans to take how it adapted the guidelines to an independent oversight board.
