Failure to heed early warning signs of drought led to tens of thousands of deaths in East Africa, says a report by Oxfam and Save the Children.

Heavy rains in Mogadishu have swept away makeshift camps housing people fleeing from famine. Channel 4 News hears from a charity worker who met a woman whose daughter was lost in the deluge.

Two women working for the aid charity Medecins Sans Frontieres at the world's biggest refugee camp, Dadaab, are kidnapped by gunmen.

Millions of people face starvation across east Africa as failed rains bring severe drought. In the refugee camp of Dadaab, numbers have swelled to critical levels as people seek food and water.

The Disasters Emergency Committee tells Channel 4 News that just over a quarter of money it has raised towards the Horn of Africa Appeal is going to Somalia, the epicentre of the drought crisis.

More than one million children have been displaced by the disaster in east Africa, and one charity tells Channel 4 News the situation in Somalia is "definitely getting worse".

The British Somali journalist Jamal Osman experiences for himself just a little of the arduous trek being endured by thousands of starving Somalis making their way to the Dadaab refugee camp in Kenya.
