The United Nations food agency has warned that across the world, 41 million people in 43 countries are at imminent risk of famine, with nearly 600,000 others in four countries already experiencing famine-like conditions.

In a statement Tuesday, The World Food Programme (WFP) 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.

The WFP, a humanitarian agency funded by voluntary donations, said it needs 6 billion dollars to immediately reach those at risk in these affected countries.
