Memorial services are being held across the region today to mark Holocaust Memorial Day.
This year it is the 70th anniversary of the liberation of the Auschwitz concentration camp in Nazi-occupied Poland and we will be across the region at a series of events.
70 years ago tonight Russian troops were advancing through southern Nazi-occupied Poland and closing in on the notorious Auschwitz death camp - the following day they liberated it.
Tomorrow survivors will gather at the site to mark the anniversary.
Our correspondent David Wood reports:
As we approach the 70th anniversary of the liberation of Jews from Nazi concentration camps, efforts are being made to record the stories of the few remaining survivors.
Filming has begun, to preserve the memories of those who left places like Auschwitz alive, using specialist technology, to allow them to interact with people, long after they have gone.
In the latest of special reports cameras have been allowed into the studio where the first of a series of interviews is being recorded in three dimensions, to save the stories of the survivors for future generations.
Michael Billington reports:
Next week marks 70 years since the liberation of the Auschwitz death camp in Poland and the annual Holocaust memorial day. For many who were freed as the war came to an end they moved to the UK to start a new life. Our correspondent David Wood has been talking to one survivor who was first urged to keep her memories hidden but is proud to share them with students.
Next week, the 70th anniversary of the liberation of the largest and most notorious Nazi concentration camp - Auschwitz in occupied Poland.
It is also Holocaust Memorial day and in the run up to it, we have a series of special reports including one from the National holocaust museum in Newark.
In Auschwitz more than a million people died.
Frank Bright was one of the survivors but his parents and most of his classmates did not get out alive.
He's 86 now and more determined than ever to keep their memories alive. You may find parts of Natalie Gray's report upsetting:
A service has been held in Leeds to commemorate Holocaust Memorial Day.
Around two hundred people attended the service, at leeds town hall, where lord mayor councillor thomas murray lit a candle to mark the liberation of Auschwitz-Birkenau concentration camp - and in memory of those who perished in the holocaust
There will be commemoration services in the region today, ahead of Holocaust Memorial day tomorrow, to mark the anniversary of the liberation of Auschwitz-Birkenau concentration camp.
In Leeds, an event at the city's town hall will be hosted by the Lord Mayor and include speakers, live music and a performance by young people. The Lord Mayor, councillor Thomas Murray said:
"The journeys and stories detailing the experiences of those people who suffered greatly during the Holocaust should never be forgotten, and events such as these are a chance to both reflect and remember those people who were both victims and survivors."
And in York this evening, those who died in Clifford's Tower will also be remembered, with a candle-lit ceremony of prayer, the laying of stones and music.
Councillor Sonja Crisp said: "These journeys affect us all. In remembering and acknowledging the past we can each help to promote a more tolerant and inclusive society for the future and not repeat the terrible mistakes of history."
Students who visited Auschwitz this week said they could not put into words the shock they felt after learning about the events which happened at the camp.
From early 1942 until late 1944, transport trains delivered Jews to the camp's gas chambers from all over German-occupied Europe.
Around 1.3m people were reported to have died there - but some say the figure could be as high as 2.5m.
