The African Union has raised concern over Russia’s attack on Ukraine and is calling for an “immediate ceasefire” to avoid a “planetary conflict”. The union’s chairperson, Senegalese President Macky Sall, and AU Commission Chairman Moussa Faki Mahamat said in a statement that they were “extremely concerned” by the invasion. The full-scale assault on Ukraine is ongoing on several fronts after Russia launched attacks from the east, north and south on Thursday.
