Pakistan's interior minister says authorities have received information one of two people believed to be contenders to succeed Baitullah Mehsud was killed in the fight. But he says the information is still being verified.
Intelligence officials believe Mehsud may have been killed in a CIA missile strike on his father-in-law's house in South Waziristan.
One Taliban commander is denying there's been any quarrel between rival factions and says he has spoken himself with one of the contenders and that he was not injured. And the other so-called contender to succeed Mehsud is even denying that the Taliban leader is dead.
There are suspicions that the Taliban commanders may be trying to keep militants unified until a successor is found.
