ISLAMABAD - Pakistan's most influential Taliban leader, Baitullah Mehsud has trained and lined up a whole new bunch of diehard commanders all set and ready to take on the security forces in case of any major offensive. "The intelligence reports from the tribal areas suggest that it's not only the threat of Baitullah Mehsud that we have to cope with but there is a large group of little known but diehard commanders who could launch attacks on security forces when they feel it is necessary for the survival of Taliban movement," said a senior official here requesting anonymity. He said that at the most the people had heard of Maulvi Faqir Muhammad, Baitullah's deputy in Bajaur, Fazlullah in Swat and Omar Khalid in Mohmand agency but there were still many others like them who could show their skills in case of need. He said that those commanders could be dubbed as second tier of Tehrik-e-Taliban Pakistan (TTP) but they could come to the front if any of the leaders at the top was removed from the scene including Baitullah Mehsud. The official said that with dozens of commanders in its fold and thousands of common fighters, TTP had become a major force in Waziristan, Bajaur and Mohmand Agencies, whereas it was increasing its influence in Khyber, Kurrum and Orakzai Agencies. He, however, refused to reveal the identity of the second tier of Taliban commanders saying it would not serve the cause of the country. Another official when contacted said that growing strength of Taliban was evident from the recent killing of Shah Khalid, a powerful Jihadi commander in Mohmand Agency by Omar Khalid, one of Mehsud's deputies. He said that earlier Shah Khalid was considered to be the most influential commander in Mohmand Agency but unlike TTP he indulged only in militancy across the border in Afghanistan. He was removed because of his alleged closeness to Pakistan's security agencies, the official said. He said that the security brass felt that in case of any major offensive against the Baitullah's followers a heavy collateral damage in the form of civilian casualties could not be ruled out. "Hence, it is wise to isolate the hardliners from those militants who want to talk and lay down their arms," the official said. He said, "It was the strategy that we were working upon and also telling the United States to give it a time to succeed as the use of force would lead to further destruction and devastation not only in tribal areas but also in settled parts of the country."
