The Pak Taliban infighting has hampered peace talks with the Nawaz government.
The infighting has claimed more than 90 lives in the tribal areas along the Afghan border, as two factions of the Tehreek-i-Taliban Pakistan (TTP), the umbrella grouping for disparate militant groups, have been locked in bloody clashes since March.
According to Dawn News, the fighting has now forced the TTP's commander-in-chief Mullah Fazlullah to appoint a mediator to try to end the feud.
A TTP insider said that the infighting has forced the Taliban leadership to postpone peace talks for the time being.
Another Taliban commander in the northwest said that 'peace talks have been halted until end of differences between the two rival groups,' the report said.
The development threatens to undermine what little progress has been made in the peace negotiations.
A commander said that the differences between the Sajna and Sheheryar groups mean differences in the Mehsud tribe and its continuation is very harmful for the Taliban, the report added.
