The Washington headquarters of a leading Muslim organization in the United States has been evacuated after the discovery of a "suspicious" substance in the mail.
Maha Sayed, staff attorney for the Council on American Islamic Relations (CAIR), said the office received an envelope on December 10 containing a note that read, "Die a painful death, Muslims," and a white powder.
CAIR Executive Director Nihad Awad said two employees were quarantined inside the building. He said one was coughing and the other complained of a headache after the piece of post was opened.
CAIR spokesman Ibrahim Hooper later said employees were allowed back into their offices after tests showed that the suspicious substance was not harmful.
The incident follows last week’s mass shooting in San Bernardino, California, by a radicalized Muslim couple.
The CAIR describes itself as an "organization that challenges stereotypes of Islam and Muslims."
