PARIS, Aug 11 (Reuters) - Restrictions on women pursuing higher education in Afghanistan are expected to exacerbate a shortage of female teachers, further diluting education quality in a country where millions of children arealready unable to attend school, UNESCO said on Wednesday. • Five years after the Taliban returned to power, about 2.4 million girls in Afghanistan are unable to attend secondary school, while more than 2million primary school children are out of school, the UN education agency said. • Women have been banned from universities since December 2022, reversing nearly two decades of progress in girls' education, and are barred from teaching boys. • UNESCO estimates Afghanistan will have a deficit of more than 11,000 qualified female teachers by 2030. • Afghanistan is the only country in the world to formally bar girls and women from accessing education after primary school.
