Another 12 Pakistani soldiers were injured when militants opened fire on the convoy after the explosion in the Kurram tribal area.
Khan said the convoy had been dispatched to provide reinforcements to the Sheendand area of Kurram, where militants had set up a hideout.
It was not immediately clear whether any miitants were killed or wounded in the clash.
More than 100 militants and dozens of Pakistani troops reportedly have been killed in the Kurram area during the past two weeks in a battle for control of a mountain route used by the Taliban to pass from the Orakzai tribal area to North Waziristan and on into southern Afghanistan.
