A small crowd gathers for the inauguration of a 'stolperstein', or 'stumbling block', in a street in east Amsterdam, where it honours the life of Ilse Wagner, a Jewish girl who was deported from the Netherlands and killed by the Nazis in the Sobibor extermination camp.
Wagner's name is familiar to those who have read Anne Frank's diary, as she was a friend of the young writer.
"This is beautiful," says Helen Romain-Levien, a relative of Wagner.
