http://timesofindia.indiatimes.com/...aida-build-dirty-bomb/articleshow/8165045.cms Did the world's most dangerous man, Osama bin Laden, who was killed by American forces on Sunday, seek nuclear weapon know how from Pakistan? His death has triggered a debate among a section of the Indian nuclear fraternity which includes two of its former chiefs, whether Pakistan backed al-Qaida's ambition to join the elite global nuclear club. Some time back the CIA and the British intelligence released documents to prove that the al-Qaida had built a small dirty bomb at a laboratory at Herat in Afghanisthan. Unlike a sophisticated nuclear bomb, a dirty bomb is a primitive device in which the radioactive material is packed with explosives which can spray a deadly cloud over an area. The documents also sought to establish that al-Qaida had prepared a training manual on how to use the weapon with a maximum effect. Bin Laden is even reported to have proclaimed that it was the religious duty of Muslim states to acquire nuclear, chemical and biological weapons to attack the west. In August 2001, a month before 9/11, two Pak nuke scientists, Chauduri Abdul Majeed and Sultan Bashiruddin Mahmood, stated to be close to the father of Pakistan's nuclear bomb, A Q Khan, met bin Laden at Kandahar in Afghanisthan and reportedly discussed nuclear technology. Against this background, former chairman of India's atomic energy commission (aec), M R Srinivasan said: "Yes, there is a degree of suspicion that some information must have gone from Pakistan to al-Qaida. But, at the same time I feel Pakistan would have restricted access to nuclear materials. I recall that A Q Khan, in one of his initial interviews, had stated that he was spreading nuclear weapons technology to Muslim nations in the cause of Islam,'' Srinivasan stated. Added Srinivasan: "Despite the suspicion that some information about nuclear weapons technology must have gone from Pakistan to al-Qaida, I would still like to believe that Pakistan will not be so irresponsible as to part with all the critical know-how to al-Qaida.'' he asked.
