Disgraced Pakistani nuclear scientist makes rare trip out of house arres

Pakistani authorities on Wednesday allowed Abdul Qadeer Khan, a disgraced scientist who confessed to passing nuclear technology to Iran, to make a rare trip from his home where he has been held under de facto house arrest since 2004. Khan's trip to express condolences for the death of a colleague follow suggestions from Pakistan's new government that restrictions on his movements could be eased. However, the authorities have ruled out allowing foreign investigators to speak to him directly about still-open questions on Pakistan's nuclear program and its proliferation activities. Reached by telephone, Khan confirmed Pakistani television reports that he visited the Academy of Sciences in the capital, Islamabad, to express condolences over the death of its secretary general, Iftikhar Malik, a friend and former colleague.
