WESTFIELD, Mass. (AP) — Muslim activists are condemning anonymous mailers targeting a Muslim-American congressional candidate in Massachusetts.

The Council on American-Islamic Relations' Massachusetts chapter says the illustrated mailers attempt to "stoke fears" of Muslims.

They criticize attorney Tahirah Amatul-Wadud for serving on CAIR-Massachusetts' board of directors and as general counsel for The Muslims of America.

The two organizations are frequent targets for right-wing groups.

The Muslims of America operates Muslim enclaves like Islamberg in New York. CAIR is often tied to fundamentalist groups like Hamas and the Muslim Brotherhood, which it denies.

Amatul-Wadud is challenging U.S. Rep. Richard Neal in the Sept. 4 Democratic primary.

CAIR says the mailers were sent to homes around Westfield following one of Amatul-Wadud's campaign events.

The organization says anyone with information should contact police or the local postmaster.
