The Interior Ministry has asked the Afghan police to seize all plastic weapons they find being sold. At the same time, the Ministry has asked that parents stop buying the toys for their children.The move has pleased children's rights activists, who believe that a "culture of violence" is so deeply engrained in Afghan society that it must be fought beginning in childhood. It remains to be seen if the ban will have any measurable effect, and if it will be accompanied by any further preventive measures, says our Observer Zakia Ahmad, a children's rights activist.
