A leader of the Islamic Center of Des Moines plans to meet with authorities to discuss a threatening note found in the center's mail.

Dr. Samir Shams, the president of the center, says he found the handwritten note Sunday morning. It said Muslims were a "vile" people and that President Donald Trump would "do to you Muslims what Hitler did to the Jews." The note was signed only "Americans for a Better Way."

Shams says Muslims have to take such notes seriously and that he planned to meet Monday with the FBI.

The Iowa chapter of the Council on American-Islamic Relations issued a news release calling for a hate crime investigation. The council says similar messages have been sent to other mosques in Iowa and elsewhere.
