At least six people were killed when a roadside bomb struck a school van carrying teachers and their children in the Bajaur tribal region of northwestern Pakistan.
Two infant children, three female teachers, and one passerby were killed in the attack, which was reportedly set off by remote control.
Reports say the van was carrying the women and the women's children to a local community school run by an aid group funded by international charities.
No group has immediately claimed responsibility for the attack, but Taliban militants often target educational institutions in the region.
The Bajaur tribal region has been the scene of several military offensives against the Pakistani Taliban and foreign militants in recent years.
