OSWIECIM, Poland (AP) — Survivors of Auschwitz-Birkenau are gathering Friday to commemorate the 78th anniversary of the liberation of the Nazi German death camp in the final months of World War II, amid the horror of war again shattering peace in Europe.

The former concentration and extermination camp is located in the town of Oświęcim in southern Poland, which during World War II was under the occupation of German forces and became a place of systematic murder of Jews, Poles, Soviet prisoners of war, Roma and others targeted for elimination by Adolf Hitler and his henchmen.

In all, some 1.1 million people were killed at the vast complex before it was liberated by Soviet troops on Jan. 27, 1945.

Today the site, with its barracks and barbed wire and the ruins of gas chambers, stands as one of the world’s most recognized symbols of evil and an admonition of “Never Again” that has been a site of pilgrimage for millions.

Yet it lies only 185 miles from Ukraine, where Russian aggression is creating unthinkable death and destruction — a conflict on the minds of many of those paying tribute to the victims of eight decades ago.

Russian President Vladimir Putin attended observances marking the 60th anniversary of the camp’s liberation in 2005. But he has been unwelcome for years now.

This year, no Russian official at all was invited due to Russia’s attack on Ukraine, according to the Auschwitz-Birkenau state museum.

Ukrainian President Volodymyr Zelenskyy marked the event with a post on his official Telegram feed that alluded to his own country’s situation.

“We know and remember that indifference kills along with hatred,” he said.

“Indifference and hatred are always capable of creating evil together only. That is why it is so important that everyone who values life should show determination when it comes to saving those whom hatred seeks to destroy.”

Bogdan Bartnikowski, a Pole who was 12 years old when he was transported to Auschwitz, said the first images he saw on television last February of refugees fleeing after Russia’s full-scale invasion of Ukraine triggered traumatic memories.

He was stunned seeing a little girl in a large crowd of refugees holding her mother with one hand and grasping a teddy bear in the other.

“It was literally a blow to the head for me because I suddenly saw, after almost 80 years, what I had seen in a freight car when I was being transported to Auschwitz. A little girl was sitting next to me, hugging a doll to her chest,” Bartnikowski, now 91, said.

Bartnikowski was among several survivors of Auschwitz who spoke about their experiences to journalists on the eve of Friday’s commemorations.

One of the others, Stefania Wernik, who was born at Auschwitz in November 1944, less than three months before its liberation, spoke of Auschwitz being a “hell on earth.”

She said when she was born she was so tiny that the Nazis tattooed her number — 89136 — on her thigh. She was washed in cold water, wrapped in rags and subjected to medical experiments.

And yet her mother had abundant milk, and they both survived. After the war, her mother returned home and reunited with her husband, and “the whole village came to look at us and said it’s a miracle.”

She read out an appeal to the next generations to be vigilant about insidious ideologies.

“No more fascism, which brings death, genocide, crimes, slaughter and loss of human dignity,” she said.

Among those expected to attend commemorations on Friday is Doug Emhoff, the husband of U.S. Vice President Kamala Harris.

The Germans established Auschwitz in 1940 for Polish prisoners; later they expanded the complex, building death chambers and crematoria where Jews from across Europe were brought by train to be murdered.

German Chancellor Olaf Scholz said, “The suffering of 6 million innocently murdered Jews remains unforgotten — as does the suffering of the survivors.”

“We recall our historic responsibility on Holocaust Memorial Day so that our Never Again endures in future,” he wrote on Twitter.

The German parliament was holding a memorial event focused this year on those who were persecuted for their sexual orientation. Thousands of gay, lesbian, bisexual and transsexual people were incarcerated and killed by the Nazis. Their fate was only publicly recognized decades after the end of World War II.

Elsewhere in the world on Friday, events were planned to mark International Holocaust Remembrance Day, an annual commemoration established by a United Nations resolution in 2005.

About 6 million European Jews were killed in the Holocaust and millions more were killed in the global war that lasted from 1939 to 1945.
