The Anti-Defamation League said Nation of Islam leader Louis Farrakhan confirmed his “status as the leading anti-Semite in America,” following a speech he gave this week in which he blamed Jews and Israelis for the deadliest terror attack in American history.

In a statement released Thursday, Abraham H. Foxman, ADL’s national director, said that Farrakhan was the “pied piper of bigotry” who has been able to “use and abuse his status as a religious leader with a large audience to obsessively harp on about perceived Jewish power and influence.”

“At a time when anti-Semitic attitudes are at historic lows, Farrakhan’s unabashed promotion of anti-Semitism is a throwback to the intolerance of another era,” Foxman said.

“Unlike most fringe anti-Semites, Farrakhan still has a significant following who not only listen raptly, but who cheer him on with every new insult.”

The ADL also noted an increase of anti-Semitic messages on the Nation of Islam’s Research Group website.

Farrakhan told members of a Chicago mosque Sunday that Israelis and “Zionist Jews” played key roles in perpetrating the 9/11 terror attacks that killed nearly 3,000 people in New York in 2001.

Delivering the second part of a lecture entitled “The Intensifying, Universal Cry for Justice,” Farrakhan asserted that Jews perpetrated the deadly attacks in order to start a war between the West and the Muslim world and claimed that the attack and “the root of terrorism was not committed by Arabs or Muslims.”

“It is now becoming apparent that there were many Israelis and Zionist Jews in key roles in the 9/11 attacks,” the Nation of Islam leader told the audience.

“We know that an Israeli film crew dressed as Arabs were filming the Twin Towers before the first plane went in. In other words — Israelis had full knowledge of the attacks.”

“We’re dealing with thieves, and liars — and murderers,” Farrakhan said, eliciting vocal approval from the audience.

Spreading one of the more common — needless to say false — 9/11 conspiracy theories, Farrakhan claimed that “many Jews received a text message not to go to work on September 11th. Who sent that message that kept them from showing up?” he asked rhetorically.

Farrakhan also alleged that “numerous” Israelis were arrested immediately after the attacks, but were later released and allowed to return to Israel.

Citing new “evidence,” Farrakhan said that the impact from the airplanes that crashed into the World Trade Center buildings would not have brought down the towers, and alleged that bombs were placed inside the buildings with full knowledge of the buildings’ Jewish owner, Larry Silverstein. He said that Silverstein was motivated to participate in the plot in order to collect billions of dollars in insurance money.

Farrakhan, who said that his opponents were trying to kill him, called on the US to conduct a new investigation into the claims.

“It now appears 9/11 was a false flag operation, which is an attack from one country but made to appear like an attack from another in order to start a war between them. Is this what friendship is?” Farrakhan concluded.
