Exhibition on Iran's executed political prisoners opens

'Omid ist mein name' - or 'Hope is my name' - is a new exhibition dedicated to the political prisoners who were executed without fair trial in Iran during the 1980s.

The killings took place after the establishment of a new Islamic Republic in Iran.

The exhibition is being held at the Anne Frank Museum in Frankfurt.
