Nuclear smuggling claims in Switzerland

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

In a documentary scheduled to air today on Swiss TV station SF1, Urs Tinner says he tipped off United States intelligence about a delivery of centrifuge parts to build nuclear weapons in Libya.

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.

The 43-year-old Tinner is suspected of supplying Khan's clandestine network with technical know-how and equipment.

Khan - creator of Pakistan's atomic bomb - sold the centrifuges to countries for secret nuclear weapons programmes.
