Russo-Ukrainian War
A report from the "Irish Times" said that the United Nations told its employees in a communications guidance to refer to the war in Ukraine as a "conflict" or "military offensive" rather than as a "war" or an "invasion", and also ordered employees to not put the Ukrainian flag on any of their social media accounts to "avoid reputational risk", in an attempt to avoid upsetting Russia. However, Stéphane Dujarric, spokesman for the secretary-general of the United Nations, wrote in an email to "The Guardian" that no such recommendation was ever issued.
