Iranian nuclear scientist Shahram Amiri 'executed'
An Iranian scientist who provided the US with information about the country's nuclear programme has been hanged for treason, the government has confirmed. Shahram Amiri was executed for giving "vital information to the enemy", a judiciary spokesman said. Amiri disappeared in Saudi Arabia in 2009 and resurfaced a year later in the US, where he claimed to have been abducted and interrogated by the CIA. He subsequently returned to Iran and was given a long prison sentence.
