American billionaire Bill Gates is donating another $258 million to the fight against malaria, which kills more than one million people each year, mostly African children.
The Bill and Melinda Gates Foundation announced Sunday it is granting the money to groups working on new drugs, a vaccine and better mosquito control to stop malaria.
A new report by a the Malaria Research and Development Alliance says the $258 million donation equals more than three-quarters of the entire global spending on research into the disease last year.
Mr. Gates told reporters Sunday it is "a tragedy that the world has done so little" to stop the disease that kills 2,000 African children every day.
Mr. Gates, who founded computer software giant Microsoft, is the world's wealthiest person.
