Known officially in Israel as Holocaust and Heroism Remembrance Day, it is Israel’s day of commemoration for the those who perished in the Holocaust at the hands of the Nazis and their allies, and for the members of the Jewish resistance in that period. In Israel, it is a national memorial day and public holiday. One of the ways it is commemorated is with the sounding of air raid sirens throughout Israel. At the sound of the siren all traffic, pedestrian and vehicular, stops for two minutes. This video clip shows how it went down at Jerusalem’s busiest outdoor market.
