A battle between rival Pakistani militant groups has reportedly killed about 70 fighters.
The clashes broke out in Pakistan's northwest frontier.
Pakistani intelligence said fighters loyal to Taliban leader, Baitullah Mehsud, and those of a rival group, were involved in the firefight.
The death toll is difficult to confirm since the area is remote and is off limits to journalists.
There have been reports in recent days of a deadly shootout between Taliban commanders trying to replace Mehsud, who was allegedly killed in a U.S. missile strike.
But neither Pakistani officials nor the Taliban have yet to provide evidence to prove if the Taliban chief was killed.
