Police in Westbrook, Maine, are investigating after notes urging violence against Muslims were found at an apartment complex where Iraqi residents live.

An Iraqi man went to police Wednesday morning after finding a typewritten note saying "All Muslims are Terrorists should be Killed."

Police canvassed the complex in the small city outside of Portland and found a second identical note on the ground. They also were told that two other notes had been found 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.
