JERUSALEM: Israelis are standing still for a nationwide moment of silence in remembrance of the 6 million Jewish victims of the Holocaust. A two-minute siren wailed across the country on Thursday for Israel's annual Holocaust Remembrance Day, when Israelis pay respects to those systematically killed by Nazi Germany and its collaborators in World War II. Buses and cars halted on streets and highways as Israelis stepped out of their vehicles and stood with heads bowed. The sombre day is also marked by ceremonies and memorials at schools and community centres. Restaurants and cafes close, and TV and radio stations play quiet music and Holocaust-themed programs. A third of the world's Jews were murdered in the Holocaust. Israel was established afterwards in 1948 and hundreds of thousands of survivors fled there.
