The UN says the famine gripping parts of southern Somalia has spread to three new areas of the country.
Officials estimate the entire south is likely to be declared a famine zone within the next six weeks.
Some 100,000 people have arrived in the capital Mogadishu in the last two months alone. Thousands more have sought refuge in Ethiopia, which is scarcely any better off.
Drought, conflict and a lack of food have left 3.6 million people at risk of starvation in southern Somalia. The drought has affected 12 million across the Horn of Africa.
The Islamic militant group Al Shabaab holds much of south and central Somalia. This means the Somali capital is the most likely place in the world for a terrorist attack, according to latest research.
