A war in Iran is reportedly threatening to cause a fresh increase in food prices across the developing world. The conflict is said to be having a ripple effect on food prices in countries such as Nigeria, and may also be exacerbated by other factors like a potential "super" El Niño event. A shutdown of the Strait of Hormuz and other disruptions are raising fears of a global food crisis, with potential impacts on hunger levels and food security in poor countries.
