The attack came in the Mir Ali area of Miranshah, the main town in the North Waziristan tribal region, a hub for Taliban and al Qaeda linked militants on the Afghan border.
Ansarul Mujahideen, a little-known militant group linked to the Tehreek Taliban Pakistan faction claimed the responsibility hours after the attack.
"It is revenge for the killing of Hakimullah Mehsud by a US drone," Abu Baseer, a purported spokesperson of the group told AFP by telephone.
"We will continue such attacks in future as drones continue to kill our people," he said.
A senior security official told AFP that "a truck laden with explosives was rammed into the checkpoint when security officials were offering evening prayers".
As a result, "five soldiers embraced shahadat (martyrdom)", the official said.
"The checkpoint has been completely destroyed and 34 injured security personnel have also been recovered," he said, revising an earlier toll of 4 people dead and 25 injured.
"Security personnel are still removing bodies from the checkpoint," he added.
The attack took place at Kharoji checkpoint, about three kilometres east of Miranshah.
Another security official confirmed the toll, adding that out of the 34 injured, 28 were soldiers and 6 from the Frontier Corps, the paramilitary group serving in Pakistan's northwest and tribal areas.
"The soldiers were offering prayers at the time of the blast," the official said.
The umbrella Tehreek-e-Taliban Pakistan faction and al Qaeda linked militants have led a bloody campaign against the Pakistani state in recent years, carrying out hundreds of attacks on security forces and government targets, concentrated largely in the northwest.

Call them by any name: terrorists, freedom fighters, strategic assets, our brothers or government supported non-state actors. They all are killing Pakistanis.
When ever Pakistan army does some operation like they did in SWAT, they bill US for all the expense money. Usually Pakistan government tries to do operations where they can kill foreign jihadis. It is all about money.
Out of curiosity, just WHO is tasked with watching for approaching vehicles and guarding the checkpoint/base/whatever while "prayers are being offered"??? It would appear that the terrorists know exactly when to approach and attack just by observing when prayers are being offered!
These are the same barbarians for which stupid PTI has been making the case.
Army please, start operation against these cave men who only understand language of force.
PTI and JI should go to Afghanistan if they have to support such ideologies.
So sad to hear. There is only one language these barbaric people understand. May ALLAH give us Peace.
@Muslim -- yes I can see you have never stepped foot in that area!
Bravo freedom fighters. keep it up.
That's a serious incident and casualties are bound to rise which calls for immediate action.
@Bilal: Last time I checked nawaz sharif wanted peace talks too, and btw he's in charge of FATA. Another man will enter jananam today whilst these Shaheeds will enter the highest place in Jannah, being killed by offering prayers, these animals cannot be called Muslims.
......and we still want to talk with them !
@Bilal: Are you insane? This is FATA and under Chaudhry Nisar, get it? Imran Khan is not the PM, Interior minister - just an MNA. Ask Nawaz Sharif or Ch Nisar & also get a life plz.
Ishaq khan @ Bilal. Imran khan is not interior minister or a prime minister, nor he heads the Armed forces. You asking the wrong person dud. Get over your prejudice first then you will have clear mind to think.**
Its pay back time....Pashtun Areas r not colonies of US or Pak.....its where warriors inhabit....
I appeal to the new army chief to start an operation against these barbarians. Then this operation should be extended to Taliban apologists in the media such as Ansar abbassi. These people have to be dealt with in order to save Pakistan from terrorism.
This is what happens if you spend less time on your duty and more time praying... Their prayers seem to be answered...
