US President Joe Biden took part in a wreath-laying ceremony at Yad Vashem on Wednesday afternoon.
The Ankor children's choir sang "A Walk to Caesarea" by Hannah Szenes, a Jewish resistance fighter who was killed in Hungary during World War II.
The president met with Holocaust survivors Rena Quint and Giselle (Gita) Cycowicz during his visit as well.
"It is a great honor to be back - back to my emotional home. We much never, ever, forget because hate is never defeated. It only hides. We must teach every successive generation that it can happen again unless we remember. That is what I teach my children and grandchildren. Never forget," wrote Biden in the Yad Vashem Guest Book.
