Israel's Holocaust memorial day begins with event marking 70 years to Warsaw ghetto uprising

Israel's annual memorial day for the 6 million Jews killed in the Holocaust has begun with a ceremony marking 70 years since the Warsaw ghetto uprising.

The uprising has come to symbolize Jewish resistance against the Nazis in World War II.

Sunday's main ceremony was taking place at Yad Vashem, Israel's official Holocaust memorial. Israel's president and its prime minister were set to speak before hundreds of Holocaust survivors and their families, Israeli leaders, diplomats and others.

The Israeli flag flew at half-staff, and a military honor guard stood at one side of the podium as poems and psalms were read and the Jewish prayer for the dead was recited.

The annual Holocaust memorial day is one of the most solemn on Israel's calendar.
