Based on a report (in Dari) sent to Stop Child Execution Campaign by the Afghanistan Independent human rights commission (http://www.aihrc.org.af/) :
The smugglers place about 200 to 1000 gram of crystal inside a tightly tied cloth covered with plastic and make the children swallow them. Then they cross the children across the border with false passports. As soon as the crystals are swollen the children have to start their journey or the bags could open if not discharged within 24 hours which would lead to the child’s death.This method of smuggling was discovered by Iranian border police in the past few years and as a result tens of Afghan children were arrested after crossing the border to Iran. Few children have already been executed by Iranian authorities while the smugglers who used these kids are still freely roaming in the Afghan villages.
