Seventy years after the liberation of Bergen Belsen, thousands of London's Jewish community gathered today to mark Jewish Remembrance Day. One of those in the crowd was 90-year-old Eva Behar - a holocaust survivor who was being held at the concentration camp the day the British forces entered.
She went on to marry one of the soldiers involved in the liberation. Toby Sadler went to meet her. His report contains some distressing images.
