For the first time, it’s been officially confirmed that the Swiss brothers Urs and Marco Tinner did work for the American Central Intelligence Agency, the CIA.

The brothers and their father have been suspected of smuggling nuclear secrets for a group that supplied weapons components to Libya.  The documents related to their case have been the subject of dispute – the Americans and some members of the Swiss government have wanted the documents destroyed.  

The Tinners and the CIA denied that they were working together but information revealed in a ruling today from the Federal Court confirms that there was a secret collaboration between them.  

The case against the Tinners continues.
