Today is a national holiday in Israel, Yom HaShoah. It is a day to honor the memory of six million Jews and many millions more who died at the hands of the Nazis.
The day is commemorated with speeches by the President of Israel, Shimon Peres and Prime Minister Benjamin Natanyahu at Yad Vashem, the lighting of six torches by Holocaust survivors, prayers by Israel's chief rabbis and two minutes of silence across the entire nation.
While the United States and other countries have Holocaust Memorial Days, many Jews around the world observe the day in solemn prayer at home and by visiting important historical sites.
