ISLAMABAD - The government is likely to ease restrictions on the movement of renowned nuclear scientist, Dr AQ Khan, who has been under house arrest since 2004, TheNation reliably learnt here on Tuesday. "There is a strong realization among the ruling circles that Dr Khan should be given some relaxation in his movements as he has been under house arrest for quite long now. Besides, the government has already declared that Dr Khan's issue is a closed chapter," said a senior official here desiring not to be named. Dr Khan was put under house arrest after he confessed to have passed on nuclear secrets to Iran, Libya and North Korea in his televised address, back in 2004. After his public confession, President Pervez Musharraf pardoned the father of country's nuclear programme. When asked what sort of relaxation was likely to be given to Dr Khan, the official said that the eminent nuclear scientist, who also suffered from low blood pressure and periodic fever, could be allowed to meet his family members and friends. "He (Dr Khan) could also be allowed to go to some restaurant for occasional meals but under stringent security arrangements," the official said. According to the official, one major reason for Dr Khan's prolonged house arrest was threats from different foreign spy organizations, such as Mosad and RAW etc. It was also believed that he had some serious threats from Al-Qaeda, which could be interested to have access to him because of its interest in nuclear weapons, he added. However, he said that despite all those threats and concerns, many in the ruling circles believed that Dr Khan had suffered a lot and he should be given some sort of relief and solace.
