April 21 Holocaust Remembrance Day
Israel begins marking Holocaust Remembrance Day at sundown on Monday with a ceremony at the national memorial to the six million Jews killed by the Nazis during World War II.

President Shimon Peres and Prime Minister Benjamin Netanyahu are due to attend the ceremony at the Yad Vashem Holocaust memorial in Jerusalem where the country's two chief rabbis will light six candles and recite the Jewish prayer for the dead.

Sirens will sound across the country at 0700 GMT on Tuesday for one minute in memory of the Holocaust victims, bringing all traffic to a halt.

More than 230,000 Holocaust survivors currently live in Israel, according to estimates from various advocacy groups, AP reports.
