The Leon Czolgosz Autonomous and Destructive Forces (, FADLC, also known as the Leon Czolgosz Autonomous Attack Fraction), were a Chilean anarchist cell formed in September 2006, known for its attacks against the National Intelligence Agency of Chile and the British embassy in Chile. The name of the group was in honor of the American anarchist Leon Czolgosz, who on September 6, 1901 assassinated then-United States President William McKinley with two bullets at point-blank range.
