Notes urging violence against Muslims discovered at an apartment complex in Maine are being investigated as a hate crime.

An Iraqi man went to Westbrook police Wednesday and told officers he had found a piece of paper that said "All Muslims are Terrorists should be Killed."

Police responded and found a second note, and were told two additional notes had been discovered by Iraqis living there.

Authorities say they don't know if the threats are related to recent reports that 38-year-old Adnan Fazeli, an Iranian who came to Maine as a refugee in 2009, was fighting for the Islamic State group when he was killed in Lebanon last year. Fazeli had lived in the Westbrook complex at one time.

The department has set up a meeting Thursday evening with Iraqi community members to address their concerns.
