TWO HARBORS, Minn. — Crew members on two U.S. Coast Guard boats fired machine guns at a floating target on Lake Superior, drawing criticism from the mayor of Duluth.
Coast Guard crews fired the M-240 machine guns about eight miles offshore from Two Harbors, said Chief Petty Office Robert Lanier, spokesman for the Coast Guard's Great Lakes district, based in Cleveland.
Duluth Mayor Herb Bergson said he had been led to believe there would be no live fire exercises during the Coast Guard's extended public comment period on the issue, which runs through Nov. 13.
Lanier said the target practice was announced on marine band radio Channel 16 more than two hours before firing began and every 10 minutes during the exercise.
