JERUSALEM (JTA) — Israeli Prime Minister Benjamin Netanyahu visited the grave of his brother, Yoni, at the military cemetery on Mt. Herzl, in advance of Memorial Day.

Netanyahu and his wife, Sara, visited the grave on Saturday night, in order to not interfere with the crowds who will visit Mt. Herzl and the more than 50 military cemeteries throughout the country on Yom Hazikaron, or Memorial Day, which starts on Sunday night.

Yoni Netanyahu was killed during a rescue operation to release hostages during Operation Entebbe in 1976.

Israel’s Memorial Day, which will honor the 23,169 casualties of war and terrorism who have been killed since 1860, will begin on Sunday night with a one-minute long siren at 8 p.m. and mark the beginning of the national memorial service at the Western Wall, which is broadcast on all Israeli television channels.

A second siren on Monday at 11 a.m. will mark the beginning of memorial services at Israel’s 52 military cemeteries.

On Monday morning, the annual ceremony in memory of victims of anti-Semitic incidents and terror attacks around the world will take place at the Jewish Agency for Israel in Jerusalem, in a program sponsored by: The Jewish Agency for Israel, the World Zionist Organization, the Jewish National Fund (KKL-JNF), Keren Hayesod-UIA, the Jewish Federations of North America (JFNA), and the Jewish Federations of Canada-UIA.

According to Jewish Agency figures, some 200 Jews have been killed in anti-Semitic terror attacks around the world since Israel’s establishment.
