Last year I spent two weeks in the Ukraine looking for mass graves using geophysics. Nost of these were from the Holocaust and other victims of genocide, but we also surveyed other sites that are culturally important to the Jewish community such as chapels and traditional cemeteries.
Over 1200 sites have already been researched and are expected of containing mass graves, but this number is likely to increase as research continues.
We are currently planning a much larger scale project to survey as many of the sites as possible.
