London (CNN Business) Amazon has removed a number of Christmas ornaments featuring images of the Auschwitz concentration camps from sale, amid anger from the museum that manages the site.

Pictures of the Nazi death camp complex were used on a variety of tree ornaments, a mouse pad and a bottle opener, which the Auschwitz Memorial described as "disturbing and disrespectful."

Images used showed the train tracks leading to the entrance of Auschwitz II-Birkenau and a number of scenes inside the camps, where around 1 million Jewish people are estimated to have been killed during World War II.

Amazon removed the products, which were being offered by third-party sellers, when the Auschwitz Memorial tweeted about them.

Selling "Christmas ornaments" with images of Auschwitz does not seem appropriate. Auschwitz on a bottle opener is rather disturbing and disrespectful. We ask @amazon to remove the items of those suppliers. https://t.co/0uG2JG558e pic.twitter.com/ucZoTWPk1W — Auschwitz Memorial (@AuschwitzMuseum) December 1, 2019

The memorial then noticed more products for sale also bearing images of the death camp , which operated in Nazi-occupied Poland. Those products also appear to have been pulled from sale.
