The US embassy said three US military personnel who were due to attend the opening of the school were killed, and two others wounded.
The embassy condemned the “vicious terrorist bombing” in the Lower Dir district, where Pakistan launched an assault to drive out Taliban militants last year.
The soldiers were in the region as part of a small US mission to train members of the Frontier Corps to better fight al Qaeda and the Taliban, Pakistan’s army said
Frontier Corps training, eh?
The Pakistanis are sure to hit back hard.
