An Estonian weekly newspaper ran a mock ad for weight loss pills using a photo of prisoners at a Nazi concentration camp.
The fake ad appeared in the humor section of the Eesti Ekspress, according to reports.
It was designed to mock a recent ad for an Estonian gas company that used a photo of the front gate of Auschwitz on its website to sell its product, Sulev Vedler, deputy editor of the newspaper, told The Associated Press. Vedler told the AP that the ad was not meant to "target" Jewish people.
The Estonian Jewish community and the Simon Wiesenthal Center in Jerusalem denounced the ad.
The gas company, GasTerm Eesti, removed the ad from its site the day after it appeared and posted an apology.
