Online Desk: A 99-year-old woman, believed to be the world's oldest primary school pupil, has died peacefully at home in Kenya, her grandson has told the BBC.

Priscilla Sitienei started developing health complications after attending class on Wednesday.

She, and her 12-year-old classmates, had been preparing for final exams set to start next week.

Ms Sitienei's story inspired a film and praise from the UN's culture and education agency, Unesco.

She grew up in a Kenya occupied by the British and lived through her country's struggle for independence.

She told Unesco last year that she wanted to motivate young mothers to return to school.
