Pakistan Prime Minister Yousuf Raza Gilani says the military operation targeting Taliban militants based in the South Waziristan tribal region is now over.Gilani told reporters in Lahore today that the anti-Taliban offensive in South Waziristan is over after nearly two months. He said the military is now focusing on the nearby Orakzai tribal region in order to chase the Pakistani Taliban leadership that is believed to have fled there from South Waziristan. In mid-October, Gilani ordered Pakistan's military to conduct the offensive, known as Operation Rah-e-Nijat or "Road to Deliverance."
