Iran has submitted evidence to the Swiss embassy in Tehran that its nuclear scientist Shahram Amiri was abducted by US intelligence agents. Iran has maintained that Amiri was kidnapped by US agents from Saudi Arabia last year. A US official has, however, dismissed the allegations. Meanwhile, the Iranian Foreign Ministry Spokesman, Mr. Ramin Mehmanparast has said that the United States is responsible for the safety of the kidnapped nuclear scientist Shahram Amiri.
