EBay has apologised after memorabilia from the Holocaust was found for sale on the site.
The company, which receives a commission on items sold and charges vendors a listing fee, released a statement saying:
We are very sorry these items have been listed on eBay and we are removing them. We don't allow listings of this nature, and dedicate thousands of staff to policing our site and use the latest technology to detect items that shouldn't be for sale.
We very much regret that we didn't live up to our own standards. We have made a donation to charity to reflect our concern.
