A British forensic archaeologist has unearthed fresh evidence to prove the existence of mass graves at the Nazi death camp Treblinka - scuppering the claims of Holocaust deniers who say it was merely a transit camp.
Some 800,000 Jews were killed at the site, in north east Poland, during the during the Second World War but a lack of physical evidence in the area has been exploited by Holocaust deniers.
Forensic archaeologist Caroline Sturdy Colls has now undertaken the first co-ordinated scientific attempt to locate the graves.
As Jewish religious law forbids disturbing burial sites, she and her team from the University of Birmingham have used ‘ground-penetrating radar’.
Her work at the site, where the Nazis tried to destroy all traces of industrial-scale killing, is being followed in forthcoming Radio 4 documentary The Hidden Graves Of The Holocaust.
