These photos show school-age members of the Basij movement, which started out as a volunteer force in the 1980s war with Iraq, but these days acts more as a domestic security force.  

Teenagers are shown undergoing military training, an important part of the Basij's training programme, and also taking part in anti-western demonstrations, patrolling the streets to catch other young people engaged in "immodest" behaviour, and taking part in highly ideological forms of recreation.
