A colouring book aimed at teaching children about the terrorist attacks of September 11, 2001 has generated controversy for its depiction of Muslims and interpretation of the events.

"It's disgusting," said Dawud Walid, director of the Michigan branch of the Council on American-Islamic Relations, who has lead the charge against what he sees as an irresponsible and dangerous book.

Cover of We Shall Never Forget 9/11 memorial colouring book for kids.

Every mention or depiction of Muslims or Islam in the book titled We shall never forget 9/11, is accompanied by the word "terrorist" or "extremist" and there are no counterbalancing images or references to the Muslims who were killed in the attacks or were among the first responders searching for survivors, Walid said Tuesday.

Nor does the book mention that the vast majority of Muslims in the United States and around the world condemn terrorism, he added.
