Thousands of young Jews from around the world are marching between the two parts of the Auschwitz-Birkenau Nazi German death camp in Poland in memory of Holocaust victims, notably some 430,000 Hungarian Jews who were murdered.

The silent annual march began Monday when the shofar, a ram's horn, sounded by the former camp's notorious "Arbeit Macht Frei" (Work Makes You Free) gate.

With Israeli flags and dressed in blue rain jackets, the participants are walking a 3-kilometer (2- mile) distance from the gate to a memorial in Birkenau, where Hungary's President Janos Ader is to make a speech to honor the victims.

During World War II, the Nazis killed some 1.1 million people at the camp, mostly Jews, but also Russians, Roma, Poles and other nationals.
