"If you are a girl in Afghanistan, the Taliban has decided your future for you. You cannot attend a secondary school or university. You cannot find an open library where you can read. You see your mothers and your older sisters confined and constrained," Yousafzai said during the 21st Nelson Mandela Annual Lecture in Johannesburg.
Yousafzai said the Taliban's actions should be considered "gender apartheid" and that it had "in effect ... made girlhood illegal."
She said international actors should not normalize relations with the Taliban, which returned to power in Afghanistan in 2021 as U.S.-led forces withdrew after 20 years of war. A Taliban spokesperson did not immediately respond to a request for comment on Yousafzai's remarks.

The Taliban say they respect women's rights in line with their interpretation of Islamic law and Afghan custom and that officials are working on plans to open girls' high schools, but after over 18 months they have not provided a timeframe. In an interview after her lecture, Yousafzai said she was concerned the Taliban would take away sciences and critical thinking even from boys.
Referring to the war in Gaza, she said she wanted to see an immediate ceasefire and for children to be able return to school and their normal lives.
She added: "We look at wars, ... especially the bombardment that has happened in Gaza, ... that has just taken that normal life away from children."
