Shops, vehicles and a restaurant were destroyed by the blast in Usturzai, which liess on a main road between the garrison city of Kohat and Hangu, most of whose population is from the Shia-Muslim majority.
The area was packed with shoppers preparing for the Eid-al-Fitr holiday, which starts when the holy month of Ramadan ends, probably on Monday in Pakistan.
The attack took place near a bus stop where passenger buses arrive and leave for towns across the north-west of the country.
Prime Minister Yousuf Raza Gilani condemned the "cowardly act of terrorism" and expressed grief over the loss of life, his office said in a statement.
Gilani "expressed the government's determination to stamp out the menace of terrorism and militancy from the country".
