World marks Auschwitz liberation
The site has become the most powerful symbol of the HolocaustWorld leaders and Holocaust survivors are holding a ceremony in Poland to mark 60 years since the liberation of the Nazis' Auschwitz death camp.
The ceremony began with a train whistle on the railway track that brought more than a million people to their deaths.
Survivors gathered in heavy snow next to the site of the German gas chambers, where Jews and others were murdered.
Auschwitz, the largest of the Nazi camps, was liberated by the advancing Soviet army on 27 January 1945.
Israeli President Moshe Katsav said the ceremony was taking place on "the largest burial ground of the Jewish people".
"It seems as if we can still hear the dead crying out," he told the crowd.
"When I walk the ground of the concentration camps, I fear that I am walking on the ashes of the victims."
HISTORY OF AUSCHWITZ
Construction began in 1940 on site which grew to 40 sq km (15 sq mile)
At least 1.1 million deaths, one million of them Jewish

Of 7,000 Nazi guards, 750 were prosecuted and punished after the war
On This Day: Auschwitz is liberated
Watch the service Polish President Aleksander Kwasniewski and Russian President Vladimir Putin also spoke. But German President Horst Koehler remained silent, in recognition of Germany's role as perpetrator of the Holocaust.
As the light began to fade, the Jewish prayer for the dead, the Kaddish was sung. It was followed by Christian prayers - Roman Catholic, Orthodox and Protestant.
Then, former inmates and veterans of the Soviet Red Army led a candle-lighting ceremony to remember the dead.
Some of the elderly survivors had been sitting wrapped in blankets against the driving snow for up to two hours before the ceremony got under way.
Some were wearing tags displaying their prison number - numbers that are still tattooed on their bodies.
Other world figures attending include US Vice-President Dick Cheney and UK Foreign Secretary Jack Straw.
The snow was falling like today. We were dressed in stripes and some of us had bare feet

Anniversary in quotes The anniversary events began in the German capital, Berlin, where parliament held a special ceremony including an address by a German-Jewish camp survivor, Arno Lustiger.
German poet and singer Wolf Biermann read out poems by a man murdered in Auschwitz.
At a forum in the Polish city of Krakow, attended by members of the Soviet unit which captured the camp, the Israeli president said the history of the Holocaust should never be distorted.
Mr Katsav warned against "negationists who play down the Holocaust" and called on the European Union to prevent a rebirth of Nazism in young Europeans.
Horror
Mr Putin spoke out against anti-Semitism and admitted that it was a problem in his country.

French President Jacques Chirac, inaugurating an exhibit in honour of French nationals interned in Auschwitz, said his country must bear its responsibility for the deportation of Jews from Nazi-occupied France.
One of the Red Army officers attending the ceremony at Auschwitz, Anatoly Shapiro, remembers leading his men into the first barracks as they entered the camp.
Mr Shapiro, now 92, told the BBC of the horror that the camp inspired in his men before they set about washing and feeding the survivors:
"Just behind the door, we saw naked women's bodies piled up. There was blood everywhere. The smell was so bad you couldn't stay in there for more than five minutes."
I seriously can't believe, it happened just 60 years ago, its unbearable to think about it really is. .
