Washington Post: An international smuggling ring created by Pakistani scientist Abdul Qadeer Khan that sold bomb-related parts to Libya, Iran and North Korea also managed to acquire blueprints for an advanced nuclear weapon, according to a draft report by David Albright, a former UN arms inspector.

The drawings, discovered in 2006 on computers owned by Swiss businessmen, included essential details for building a compact nuclear device that could be fitted on a type of ballistic missile used by Iran and more than a dozen developing countries, the report states.

The computer contents -- among more than 1,000 gigabytes of data seized -- were recently destroyed in a controversial decision by Swiss authorities under the supervision of the IAEA.
