Teenager Malala Yousafzai was at school in the city of Birmingham in central England when she was told she had won the Nobel Peace Prize on Friday, a spokeswoman said.
"Malala is at school as normal today," she said, adding that the 17-year-old would hold a press conference later on Friday.
Malala attends Edgbaston High School, a private school in an upmarket part of Birmingham.
After being shot by the Taliban in October 2012, Malala was treated at a hospital in Birmingham.
She started at her school in the city in March last year.
