Malala Yousafzai tells Muslim leaders not to 'legitimise' Taliban
"Do not legitimise them," she said at a summit on girls' education in Muslim nations being held in Pakistan's capital Islamabad.
"As Muslim leaders, now is the time to raise your voices, use your power. You can show true leadership. You can show true Islam," said 27-year-old Yousafzai.
The two-day conference has brought together ministers and education officials from dozens of Muslim-majority countries, backed by the Muslim World League.
Since sweeping back to power in 2021, the Taliban government has imposed an austere version of Islamic law that the United Nations has labelled "gender apartheid".
Their curbs have shut women and girls out of secondary school and university education, as well as many government jobs, and seen them sequestered out of many aspects of public life.
Delegates from Afghanistan's Taliban government did not attend the event despite being invited, Pakistan Education Minister Khalid Maqbool Siddiqui told AFP on Saturday.
"Simply put, the Taliban do not see women as human beings," Yousafzai told the conference.
"They cloak their crimes in cultural and religious justification."
Yousafzai was shot in the face by the Pakistani Taliban when she was a 15-year-old schoolgirl in 2012, amid her campaigning for female education rights.
Her activism earned her the Nobel Peace Prize in 2014, and she has since become a global advocate for women and girls' education rights.
"The Taliban are explicit about their mission: they want to eliminate women and girls from every aspect of public life and erase them from society," she told the conference.
While there is outcry in much of the international community over the Taliban government curbs, nations are divided over how to engage with Kabul's rulers on the issue.
Some countries argue they should be frozen out of the diplomatic community until they backtrack, while others prefer engagement to coax them into a U-turn.
No country has officially recognised the Taliban authorities, but several regional governments have engaged on the topics of trade and security.
