Several mosques across the U.S. have been receiving threatening letters warning of a Muslim genocide. The identical letters, addressed to the “the children of Satan,” has shown up in seven states so far.

The handwritten and photocopied letters praise President-elect Donald Trump, who according to the letter, will “cleanse America.” The Council on American-Islamic Relations (CAIR) has already called on officials to step up security at mosques.

“There’s a new sheriff in town — President Donald Trump. He’s going to cleanse America and make it shine again. And, he’s going to start with you Muslims,” the letter, signed by “American for A Better Way,” said, adding: “And, he’s going to do to you Muslims what Hitler did to the jews (sic).”

More than 700 reports of hate crimes against Muslims, African-Americans, Asians, immigrants, women and gays across the U.S. have been reported since Election Day, according to Southern Poverty Law Center.
