NAIROBI, Kenya (AP) – Ukraine’s leader has told the African Union that the continent has been “taken hostage” in Russia’s invasion of Ukraine amid catastrophically rising food prices. President Volodymyr Zelenskyy’s closed-door speech Monday followed weeks of requests for him to address African nations. Many of them retain close ties to Russia and failed to support a U.N. General Assembly resolution condemning the invasion. Ukraine and the West hope to weaken those ties by emphasizing that Russia’s actions are to blame for dramatic shortages of wheat and edible oils and skyrocketing food and fuel prices across Africa.
