The sirens wailed across Israel, and people everywhere observed two minutes of silence for the 6 million Jews killed by the Nazis during World War II. Traffic came to a standstill, and people got out of their cars and stood at attention on the streets. Places of entertainment were closed. Radio and TV stations cancelled regular programming and focused on Holocaust Remembrance Day with documentaries, interviews and discussions. Six torches were lit by Holocaust survivors at the main ceremony at the Yad Vashem Holocaust Memorial, in memory of the 6 million victims. After lighting the torch, each survivor gave a personal testimony.
