Aid drops have begun across flood-hit Kenya where nearly two million people are facing serious health threats including cholera and malaria.

A US-African combined task force has dropped 240 tonnes of supplies in the form of relief aid packages from the air in eastern parts of the country.

Around 700,000 people in the region, including Somali refugees, are thought to be in need of the supplies, reports ITN.

And as many as 1.8 million people are at risk from killer diseases such as cholera, measles and malaria.

David Okello, the World Health Organisation's representative in Kenya, said: "People are dying from diseases related to the water and sanitation situation. Malaria will become a very serious problem in the weeks to come."

Gordon Denoon, of the charity Care International, said: "We have taken these measures to try and bring in supplies through an airdrop.
