The Pakistani government has received reports that shooting broke out between two rivals for the leadership of the Pakistani Taliban, and one of them may have been killed, the interior minister said.

Pakistani news channels were carrying unconfirmed reports that Hakimullah Mehsud, one of the movement's most powerful commanders, had been killed at a shura, or council meeting, held to decide who would succeed slain leader Baitullah Mehsud.

"The infighting was between Wali-ur-Rehman and Hakimullah Mehsud," said Interior Minister Rehman Malik. "We have information that one of them has been killed. Who was killed we will be able to say later after confirming."

A Taliban official in South Waziristan, where the meeting took place, said that the government had fabricated reports of fighting between the different factions.

Noor Said, who had been a deputy spokesman under Baitullah, said: "There was no fighting in the shura. Both Wali-ur-Rehman and Hakimullah are safe and sound."

Western governments with troops in Afghanistan are watching to see if any new Pakistani Taliban leader would shift focus from fighting the Pakistani government and put the movement's weight behind the Afghan insurgency led by Mullah Mohammad Omar.

An intelligence officer in South Waziristan said he had reports that Hakimullah Mehsud died in the shooting after heated exchanges between the rivals at the meeting held around 4:30 p.m. (6:30 a.m. EDT).

"According to reports Wali-ur-Rehman fired and killed Hakimullah Mehsud," the official said.

State-run Pakistan Television said there were reports that both leaders might have been killed in a shoot-out.

The shura was called in Taliban-controlled territory in Waziristan, a northwest tribal region bordering Afghanistan.
