The World Food Programme has warned that some 41 million people in 43 countries are at imminent risk of famine.

In a statement, the United Nations agency said nearly 600,000 people in four countries are already experiencing famine-like conditions. 

The agency said wars, climate change and economic shocks have been driving the increase in hunger while soaring prices for basic items compound existing pressures on food security this year.

Famine-like conditions are present this year in Ethiopia, Madagascar, South Sudan and Yemen, as well as in pockets of Nigeria and Burkina Faso.

The WFP said that it needs to raise $6bn immediately to reach those at risk in 43 countries.
