The Afghan Education Ministry says 59 children and five teachers were among those killed in this week's suicide bombing in northern Afghanistan.
A ministry spokesman says the children were lined up outside a sugar factory to welcome a visiting delegation of parliament members, when the suicide bomber detonated explosives.
The spokesman also says the education minister has ordered that students may not take part in such events in the future.
Six lawmakers were among at least 75 people killed in Tuesday' s attack, the nation's deadliest suicide bombing since the fall of the Taliban in 2001.
A Taliban spokesman denied responsibility for the attack, which occurred in Afghanistan's relatively peaceful north.
