A former MI5 intelligence officer who has said that the Sept. 11, 2001 terrorist attacks were orchestrated by the U.S. government “as a pretext for war and… to erode our freedom” has been removed from a June 6 United Nations panel discussion in New York.

B’nai B’rith International, a Jewish humanitarian, human rights and advocacy group, had written to U.N. Secretary-General Ban Ki-moon and to the Permanent Mission of Switzerland to the United Nations to request that the 9/11 conspiracy theorist, Annie Machon, be removed from the panel.

In addition to her views on 9/11, Machon is known for claiming the Israeli Mossad was behind the 1994 bombing of Israel’s embassy in London. “Her outrageous and offensive views do not deserve a prominent platform—let alone in the city most scarred by the horrific events of 9/11,” B’nai B’rith said in a statement after the announcement of Machon’s removal from the program.
