Hidden in the maze of mud-walled alleys in the Loy Wiyala district of Kandahar, Amina, 16, is taking her first, secretive steps towards becoming a teacher.
Banned by her father Abdul from making the short walk to school, she uses a clandestine classroom to impart her smattering of knowledge to younger sisters poring over textbooks scattered across a rug.
This is not a tale of a conservative parent depriving his daughter of an education, but an Afghan family braving the risk of Taliban violence to give their girls the chance to learn.
Abdul is one of a number of anxious fathers who have set up underground schools to allow his daughters to continue studying in defiance of an escalating campaign of insurgent attacks designed to thwart a major Nato operation to secure the city.
“I went to school in Kandahar city for a while, but now we are too scared,” said Amina. “I think it is important that we all learn as much as we can at home until the situation for us improves. I want to be a teacher one day and go to teacher training college.”
Gains in promoting female education, which was banned under the Taliban, have often been cited by Western politicians seeking to buoy support for the nine-year war among increasingly sceptical publics. But some of the initial progress has been eroded by a surge in violence, particularly in the south.
