On Thursday, March 10, 1977, in Washington, D.C., a small group of members of an otherwise inconspicuous black sect of Muslims precipitated the first hostage situation in the United States executed by ideologically motivated and organized terrorists. Armed with guns and machetes, the band of Hanafi Muslims seized hostages at the national headquarters of the B'nai B'rith, the Jewish social service agency; the Islamic Center; and the City Council chambers in the District of Columbia Building. The small group of heavily armed men created a drama that spread fear throughout Washington. Security at government buildings was intensified, and protection was provided for City Council members and several congressmen.
