ISLAMABAD - Pakistans security forces will launch a large-scale military operation against all the Taliban commanders in Waziristan along with the ongoing air offensive against Baitullah Mehsud if they failed to accept the governments demand for their detachment from the Tehreek-e-Taliban Pakistan (TTP) chief. The Taliban leaders in Waziristan, other than Baitullah, including Hafiz Gul Bahadur, Mullah Nazir and Siraj Haqqani, the son of most influential militant commander in the region, Jalaluddin Haqqani, have been asked to refrain from extending support to the TTP chief in the face of the military operation. Hafiz Gul Bahadur has carried out a couple of deadly assaults against Pakistani security forces in the areas under his control in North Waziristan in the recent past whereas intelligence reports suggest that other militant commanders are also expected to side with Baitullah when the ground offensive is launched against him. The Taliban commanders have been clearly told that the security forces will not hesitate from operations against all of them if they decided to side with Baitullah who is responsible for dozens of suicide bombings and other gory acts of subversion on Pakistani soil, said a well placed source asking for anonymity. After success against Taliban militants in Swat, Buner and Dir, the Pakistani security forces are face-to-face with the tough task of military operation against Baitullah, who is considered to be the most dangerous local militant commander based in the harsh terrain of South Waziristan. Pakistani air force is already engaged in carrying out strikes on the militants hideouts in different areas of South Waziristan controlled by Baitullah. However, despite the announcement by the government several weeks ago to launch full-fledged offensive against the TTP chief, no operation has been launched so far. An official here when contacted confirmed that the Taliban commanders sans Baitullah have been contacted and told not to attack the military convoys on way to Baitullahs areas. He also acknowledged that talks were underway with the Taliban commanders to isolate the TTP chief. However, he refused to say anything about the likely operations against them in case they refused to accede to the governments demand of not siding with Baitullah. He said that it was true the operation against Baitullah would be a difficult task to achieve but the forces were fully prepared to achieve that goal. Moreover, he said that before launching any ground operation against Baitullah the government wanted to ensure complete restoration of peace and security in Swat, Buner and Dir.
