Facebook has removed US President Donald Trump's ad over 'Nazi hate symbol,' BBC reported.

The ad had an inverted red triangle similar to that used by the Nazis to label opponents.

"We don't allow symbols that represent hateful organisations or hateful ideologies unless they are put up with context or condemnation," the social network's head of security policy, Nathaniel Gleicher, noted. "That's what we saw in this case with this ad, and anywhere that that symbol is used we would take the same actions."

Tim Murtaugh, a spokesman for the Trump campaign, said in a statement: "The inverted red triangle is a symbol used by antifa, so it was included in an ad about antifa."

"We would note that Facebook still has an inverted red triangle emoji in use, which looks exactly the same," he added.
