Democratic Congresswoman Rashida Tlaib faced a firestorm of criticism on Sunday after retweeting a false assertion on the micro-blogging website accusing Jews of murdering a Palestinian child in Jerusalem, with critics describing the claim as a “blood libel.”

Eight-year-old Qais Abu Ramila was found dead on Saturday in Jerusalem’s Beit Hanina neighborhood after being missing for several hours. Authorities have concluded that Ramila died of accidental drowning in a reservoir swollen by recent rainstorms.

Rumors swirled, however, that he had been kidnapped and murdered by Jewish “settlers,” causing clashes with police when a mob of rock throwers attempted to invade an adjoining Jewish neighborhood.

Veteran Palestinian official and legislator Hanan Ashwari tweeted an accusation that Ramila had been killed by Jews, which was then retweeted by Tlaib, who is Palestinian-American. Originally from the account “realSeifBitar,” the tweet claimed Ramila was “kidnapped by a Herd of violent Israeli settlers, assaulted, and thrown in a water well.”

Ashwari later apologized for the unfounded accusation. Tlaib deleted the offending tweet but has not apologized thus far.

Israel’s Consul General in New York Dani Dayan also slammed Tlaib, tweeting, “I am always extremely cautious in criticizing US elected officials. However when an American elected official retweets an unfounded blood libel against Jewish Israelis, I cannot remain silent. Congresswoman @RashidaTlaib just did.”

This is not the first time Tlaib has been involved in a “blood libel” scandal. Last year Tlaib was banned from visiting Israel, after which it was discovered that her visit had been arranged by the organization Miftah, which Business Insider revealed has praised suicide bombers, reprinted neo-Nazi literature, and claimed Jews consume the blood of Christians as a Passover ritual — the historic blood libel which was common during the Middle Ages.
