IN March 2010, Khalid Khawaja along with Colonel Imam (widely believed to have trained Mullah Omer and recipient of a piece of Berlin Wall from Mr George Bush in appreciation of his help in the Afghan war) and Asad Qureshi, a British journalist of Pakistani origin, was kidnapped by a militant group calling itself ‘Asian Tigers’. Khawaja had become famous when he announced recently that he had accompanied Mr Nawaz Sharif in some five or six meetings with the Al Qaeda chief Osama bin Laden (prior to 9/11 and apparently when Mr Sharif was still the CM of Punjab state in Pakistan) and had received six million dollars. When Mr Sharif denied that such a meeting had ever taken place, Khawaja challenged Mr Sharif to prove him wrong and promised to present all the necessary proof to prove that such meetings did take place. It is also reported that such was the degree of fear of the militant’s attack that local people, though they had seen the body, didn’t pick it up till a ‘jirga’ authorised the local administration to retrieve it. They had gone missing after traveling to North Waziristan as per advice from ex-senior officers of Pakistani Army and ISI to interview Taliban and Al Qaeda leaders. They were working on a documentary and were reportedly invited to the tribal areas by Taliban militants. One wonders as to why Khawaja was murdered while the other two were released. By any chance, were some of the demands (like the release of Afghan Taliban commanders Mullah Abdul Ghani Baradar, Mullah Abdul Kabir and Mullah Mansoor Dadullah, who are in Pakistan’s custody) of the abductors met after the murder of Khawaja? Had he become a marked man for spilling the beans regarding Mr Sharif and bin Laden? Or is it due to internal discord and rivalry amongst various militant organisations?
