Nigeria said it would ask the IMF and the World Bank for support, as the effects of the Iran war deepen in Africa’s most populous nation.

However, the war’s downstream impacts threaten the country’s ambitious economic overhaul. Despite recently launching the continent’s biggest refinery — which could become the world’s largest — Nigeria remains reliant on imported fuels, while a fertilizer crunch could aggravate a widespread humanitarian crisis.
