SEATTLE (AP) — Civil rights groups and lawmakers are demanding information from federal officials following reports that dozens of Iranian-Americans were held up and questioned at the Canadian border as they returned to the United States.

The Washington state chapter of the Council on American-Islamic Relations says more than 60 Iranians and Iranian-Americans were detained and questioned at the Peace Arch Border Crossing in Blaine.  A U.S. Customs and Border Protection spokesman is denying reports that Iranian-Americans were detained or refused entry because of where they were born.
