Pakistan's military began its offensive in South Waziristan in mid-October
Pakistan's prime minister has said its military has completed an offensive against the Taliban in the tribal region of South Waziristan.
Yousuf Raza Gilani told reporters in Lahore the operation might now move north to the Orakzai region, where many militants are thought to have fled.
The Pakistani army has not yet commented on Mr Gilani's remarks.
However, correspondents say Mr Gilani's words do not mean the army is pulling out of South Waziristan.
Military sources have told the BBC that the army is still facing pockets of resistance there.
The Pakistani military launched its offensive in South Waziristan, in the tribal area bordering Afghanistan, in mid-October.

"The operation in South Waziristan is over. Now there are talks about Orakzai," Mr Gilani told reporters in televised remarks on Saturday.
The BBC's Orla Guerin in Islamabad says the prime minister did not elaborate on the scale of any possible offensive in Orakzai, also in the lawless tribal belt.
The military operation in South Waziristan was the biggest in years, our correspondent says, with 30,000 troops sent into battle.
The army has managed to drive many militants from their main bases but their leaders have not been arrested and are thought to have escaped into other areas.
Hundreds of people have been killed in revenge attacks around Pakistan, she adds.
A number of air strikes have targeted militant targets in Orakzai in recent weeks.
The United Nations says more than 40,000 civilians have left their homes in Orakzai and are in need of humanitarian assistance.
Pakistani Prime Minister Yousaf Raza Gilani announced that the military operation targeting Taliban militants based in the  tribal region is now over, after nearly two months.

He commented that the military is now focusing on the nearby Orakzai tribal region, in order to pursue the Pakistani Taliban leadership that is believed to have fled there from South Waziristan. There recently have been heavy artillery and air strikes in the area.

"The operation in South Waziristan is over. Now there are talks about Orakzai," Gilani said earlier today to reporters in a televised speech

In mid-October, Gilani ordered Pakistan's military to conduct the offensive, known as Operation Rah-e-Nijat or "Road to Deliverance."

Military officials say more than 600  members and some 80 soldiers have been killed in the operation near the Afghan border. These numbers have not been independently verified because, except for a few military-organized trips, the military has largely closed the area to journalists and aid agencies. The United Nations reported that about 40,000 of people have fled the region, and need humanitarian aid.

The Pakistani military has said the goals of the offensive were to clear Taliban-controlled areas and force the group's leaders to take refuge in scattered villages. Once that was achieved, the military said it would be easier for the army to conduct intelligence-led operations to capture or kill these leaders, including Pakistani Taliban chief .

Pakistani officials have blamed Mehsud's organization for a series of high profile attacks across the country that has killed more than 500 people since the beginning of October.
