A hat shop in slot Nashville, Tennessee, has drawn condemnation and protests after it advertised an anti-vaccine yellow star like those forced on Jews by Nazi Germany.
The shop, Hatwrks, said in a now-deleted Instagram post that it was selling the patches for $5 (£3.50).
The shop was criticised online and targeted by protesters, who held a sign saying "no Nazis in Nashville".
A local rabbi said the star was an insult to Jews killed under the Nazis.
"Using the yellow star, or any holocaust imagery for anything, is a disservice to the memory of the six million Jews who were systematically murdered during the Holocaust," a local rabbi, Laurie Rice, told Nashville TV station WSMV.
In a later Instagram post, the shop apologised "for any insensitivity". It said it did not "intend to trivialise the Star of David or disrespect what happened to millions of people".
During the pandemic some conspiracy theorists have been denounced for making extreme comparisons between Covid-19 measures and the fascist policies of Nazi Germany.
This week Republican congresswoman Marjorie Taylor Greene was criticised for equating Covid mask mandates with Nazis forcing Jews to wear yellow stars.
