A high school teacher allowed a group whose declared mission is to "raise an awareness of the danger of Islam" to distribute literature in his class, including a handout titled "Do Not Marry a Muslim Man," according to an advocacy group.

The Council on American-Islamic Relations says a representative from the Kamil International Ministries Organization, based in Raleigh, spoke to a ninth-grade world history class at Enloe High School and distributed the literature, which also discussed Jesus.

The father of a Muslim student reported the incident, said CAIR spokesman Ibrahim Hooper. The council wrote to Wake County schools Superintendent Del Burns asking that the incident be investigated and that the teacher be disciplined.

Burns had not received the letter, but an investigation is under way and officials will take appropriate disciplinary action, district spokeswoman Kristin Flenniken said.

The teacher has not been named. A call by The Associated Press to the high school's principal, Beth Cochran, was not immediately returned Wednesday.

On its Web site, Kamil describes itself as a Christian group "dedicated to teaching the truth about Islam" and says its mission "is to raise an awareness of the danger of Islam."

A phone number for the organization could not be found. An e-mail to the group wasn't immediately returned Wednesday.
