Both factions are part of the Tehrik-e-Taliban Pakistain (TTP) umbrella group, which has been waging a bloody seven-year insurgency against the Pak state.
The clash started a few days ago and the cause of infighting was said to be over interference in matters inside one another's domains.
In the latest clash, six Taliban fighters were killed in a remote controlled IED attack on the vehicle of Hakimullah Mehsud group's top commander Sheryar Mehsud in Shawal area of North Waziristan Agency.
Official sources said that the vehicle of Sheryar Mehsud was targetted by rival Khan said Sjana group as the two groups continue to target each other.

The top TTP leadership has also reached Waziristan to resolve the conflict.
On the other hand, the bully boy outfit's leadership is also divided on the ceasefire with the government as no formal extension in ceasefire has been announced despite the end of the earlier deadline of April 10 yesterday.
Cause for strife
Fighters from both sides have been launching attacks in the areas of Shawal, Shaktoi, Makin and Tank with heavy ammunition and artillery in an attempt to destroy one another's sanctuaries.
Moreover, the internal strife between the two groups is now spilling onto the other areas of the region.
The TTP has remained silent on the matter of infighting in which over 30 deaths have been reported over a couple of days.
The festivities first erupted on Sunday in Shawal between supporters of Khan Said Sajna and followers of the late Hakimullah Mehsud group.
Militant sources had earlier suggested that differences emerged after Sajna, a senior commander, was rejected for the TTP leadership, after then-leader Mehsud was killed in a US drone strike last November.
The TTP has long been driven by infighting.
Sajna had been seen as a strong candidate to become TTP chief following Mehsud's death. But the movement's ruling council at the last minute elected Mullah Fazlullah
...son-in-law of holy man Sufi Mohammad. Known as Mullah FM, Fazlullah had the habit of grabbing his FM mike when the mood struck him and bellowing forth sermons. Sufi suckered the Pak govt into imposing Shariah on the Swat Valley and then stepped aside whilst Fazlullah and his Talibs imposed a reign of terror on the populace like they hadn't seen before, at least not for a thousand years or so. For some reason the Pak intel services were never able to locate his transmitter, much less bomb it. After ruling the place like a conquered province for a year or so, Fazlullah's Talibs began gobbling up more territory as they pushed toward Islamabad, at which point as a matter of self-preservation the Mighty Pak Army threw them out and chased them into Afghanistan...
