Four missiles were fired from Afghanistan into Kurram Agency on Sunday.
Political administration has confirmed that one of the four missiles hit a shop in Shankak area of Kurram Agency whereas the second landed near a mosque.
The shop was completely destroyed in the missile attack.
The other two missiles landed in a graveyard located in Kharpalan area of near Kachkeena.
At least 24 people have been killed and 90 others have been injured in a bomb blast in the Shia-dominant city of Parachinar.
Jamaat-ul-Ahrar (JuA), a faction of the umbrella Tehreek-e-Taliban Pakistan, or Pakistani Taliban, swiftly claimed the attack in a message sent to AFP.
The attack comes after a wave of militant violence killed 130 people across Pakistan in February, unnerving citizens who had been emboldened by improving security and prompting a military crackdown.
The government of Pakistan had closed the Pak-Afghan border at Torkham and Chaman following a wave of terror attacks in the country.
