Man 'tipped off CIA about Khan case'

A Swiss man suspected of involvement in the world's biggest nuclear smuggling ring claims he supplied the CIA with information that led to the breakup of the black market network led by Pakistani scientist Abdul Qadeer Khan.

In a documentary scheduled to air yesterday evening on Swiss TV station SF1, Urs Tinner says he tipped off US intelligence about a delivery of centrifuge parts meant for Libya's nuclear weapons program.

The shipment was seized at the Italian port of Taranto in 2003, forcing Libya to admit and eventually renounce its efforts to acquire nuclear weapons.
