Bill Gates to give most of his $200bn fortune to Africa

Microsoft founder Bill Gates says that most of his fortune will be spent on improving health and education services in Africa over the next 20 years.

The 69-year-old said that "by unleashing human potential through health and education, every country in Africa should be on a path to prosperity".

Speaking in Ethiopia's capital Addis Ababa, he also urged Africa's young innovators to think about how to build Artificial Intelligence (AI) to improve healthcare on the continent.

Gates announced last month that he would give away 99% of his vast fortune - which he expects to reach $200bn (£150bn) - by 2045, by when his foundation planned to end its operations.
