The British government was due to face questions in parliament on Monday over revelations that asylum seekers were forced to wear colored wristbands in order to claim food at a center in Wales, AFP reports.
The Welsh Refugee Council (WRC) likened them to the yellow stars Jewish people were made wear in Nazi Germany, but the company using the wristbands said it was only a practical measure to allow migrants to claim meals.
"We have raised the matter many times with the Welsh Government. It harks back to the Nazi regime with people being forced to wear a Star of David and stand out," said WRC policy officer Hannah Wharf.
"It's absolutely appalling, it is treating people like lesser beings. It is treating them like animals lining up to feed."
Contacted by AFP, Clearsprings, the contractor running the Lynx House centre in the Welsh city of Cardiff, could not immediately comment.
