Israeli Prime Minister Ariel Sharon has arrived in Poland for the annual March of the Living at the site of two Nazi death camps.

Top Polish officials are expected to join the Israeli leader and about 20,000 others in the three-kilometer walk from the Auschwitz to the Birkenau camps, as the world marks the 60th anniversary of the end of WWII. Holocaust survivors are joining the march between the camps were the Nazis killed more than one million Jews during the war.

Commemorations were also held in Israel as sirens blared and the nation stopped for two minutes to honor the victims. At ceremonies in Jerusalem Wednesday, Mr. Sharon said Jews will never again be without protection, a home, and refuge.
