The Chairman of the National Holocaust Centre this week paid tribute to the estimated one million victims of the Rwandan genocide to mark the 20th anniversary of the beginning of a devastating 100-day slaughter.

It is thought 1,000,050 Rwandans perished in three months of machete and gunfire attacks, mostly aimed at the minority Tutsi population by extremist Hutus.

Henry Grunwald said: “I’ve been representing the National Holocaust Centre at Kwibuka 20, the 20th anniversary commemoration of the genocide. The world let Rwanda down. This was a genocide that could, and should, have been prevented.

“As a Jew whose father’s family was murdered in the Shoah, I empathise with all those who lost their families.

“I can’t imagine what it was like to have their families murdered in front of their eyes.”
