New Delhi: Afghan women around the world are protesting the Taliban's new hijab diktat in schools by posting photos of themselves wearing colourful traditional dresses on social media, CNN reported.

The Taliban have mandated the segregation of genders in classrooms and said that female students, lecturers and employees must wear hijabs in accordance with the group's interpretation of Sharia law.

Photos have emerged of a group of female students wearing head-to-toe black robes and waving Taliban flags in the lecture hall of a government-run university in Kabul.

Other Afghan women responded by posting pictures of themselves in bright and colourful traditional Afghan dresses a stark contrast to the black hijab mandate outlined by the Taliban.

Bahar Jalali, a former faculty member of the American University of Afghanistan according to her LinkedIn profile, helped kick off the picture posting campaign, according to other women who shared photos on Twitter., CNN reported.

Jalali tweeted a picture of a woman in a full black dress and veil and said: "No woman has ever dressed like this in the history of Afghanistan. This is utterly foreign and alien to Afghan culture. I posted my pic in the traditional Afghan dress to inform, educate and dispel the misinformation that is being propagated by Taliban."

Other Afghan women soon followed her lead on social media, the report added.

Waslat Hasrat-Nazimi, head of the Afghan service at DW News, tweeted a picture of herself in traditional Afghan dress and headdress with the comment: "This is Afghan culture and this is how Afghan women dress."

Shekiba Teimori, an Afghan singer and activist who fled Kabul last month, told CNN that the "hijab existed before Kabul's fall. We could see Hijabi women, but this was based on family decisions and not the government."

She said before the Taliban came to Afghanistan, her ancestors were "wearing the same colourful Afghan dresses you see in my pictures".
