Senegalese President and African Union Chair Macky Sall urged Ukraine to demine waters around its Odessa port to ease much needed grain exports from the war-torn country, Agence France-Presse reported. Russia’s invasion of Ukraine and Western sanctions have disrupted grain deliveries from the two countries, fueling fears of hunger around the world.

Cereal prices in Africa — the world’s poorest continent — have surged because of the slump in exports, sharpening the impact of conflict and climate change and sparking fears of social unrest, AFP reported. If wheat exports do not resume from Ukraine, Africa “will be in a situation of very serious famine that could destabilize the continent”, Sall told French media outlets France 24 and RFI.

Russia and Ukraine produce 30 percent of the global wheat supply, AFP reported.
