Survivors and world leaders are marking Holocaust Memorial Day with remembrance services and events.
It honours the six million Jewish people murdered, alongside the millions of other people killed under Nazi persecution of other groups.
The day also marks the 78th anniversary of the liberation of Auschwitz-Birkenau death camp, in what was then-Nazi-occupied Poland.
Set up in 1940, Auschwitz was initially intended to house Polish political prisoners – but it eventually became the largest of the Nazis’ extermination camps, where Adolf Hitler’s plan to kill all Jewish people – the “Final Solution” – was put in to practice.
About 1.1 million people were murdered there, mostly Jewish.
Here are some of the memorial events that took place during this year’s Holocaust Memorial Day.
