Belgian Police Find Video of Nuclear Official at Home of Muslim Terrorist

PARIS — The police in Belgium have retrieved 10 hours of video footage of a Belgian nuclear official from the home of a suspect in the November Paris attacks, Thierry Werts, a spokesman for Belgium’s federal prosecutor, said on Thursday.

A person close to the investigation, speaking on the condition of anonymity, said the footage indicated that a terrorist network involved in the coordinated attacks on Nov. 13 that left 130 dead may also have intended to obtain radioactive material for terrorist purposes.

The purpose of the footage is not clear, but one theory is that it could have been used to plan an abduction of the official and to obtain radioactive material by force, possibly for use in a dirty bomb.
