A Czech man has gone on trial in Switzerland accused of breaking export rules by selling restricted goods to Iran.
The unidentified man is accused of exporting electronic components to companies in Malaysia and Hong Kong between 2004 and 2006. Prosecutors say the companies are known to be linked to Iran's armament program.
Prosecutors said the 61-year-old man failed to declare the exports to Swiss authorities as he was ordered to do in August 2004.
The Federal Criminal Court in Bellinzona is expected to rule in the case on Thursday.
Swiss firms have come under scrutiny in the past for selling restricted goods to Iran.
