Heads of state, high-ranking officials from other countries, people who survived the Holocaust are present at the solemn ceremony. In the morning of the next day, a two-minute siren sounds that can be heard throughout the country. As soon as the sound of the siren sounds - life freezes all over Israel. Businesses stop, people freeze in the streets, drivers park their cars on the roadside - everyone remembers the Jews - victims of the Holocaust. After the end of the signal, the first persons of the state, representatives of public associations lay wreaths on the square of the Warsaw Ghetto in Yad Vashem. Millions of Jews living in Israel and beyond are praying that the times of destruction and horror will never be repeated.
