Israel's President Reuven Rivlin visited the attic of a Danish church where Jews were hidden as part of commemorations to mark the 75th anniversary of their rescue from the Nazis.
The German representative in occupied Denmark was ordered by Adolf Hitler in September 1943 to begin rounding up the country's Jewish population for deportation to concentration camps.
But local people rallied to help nearly 8,000 Jews escape across the Øresund strait to neutral Sweden.
Three Danish Holocaust survivors – Tove Udsholt, Hanna Skop and Ib Katznelson – who were rescued in the operation had the opportunity to meet President Rivlin during his visit on Thursday.
