At least 6 people injured after Boston duck boat overturns near entrance to popular tourist attraction

A duck boat overturned Saturday at a popular tourist attraction in Boston, Massachusetts, injuring at least six people and prompting a major emergency rescue response.

The boat tipped on its side at a Cambridge boat ramp near the entrance to the Charles River, state police told Fox News Digital. None of the passengers wound up in the water, police said.

The Cambridge Police Department (CPD) said some of the injuries were classified as minor, with two considered "more serious."

Everyone aboard the vessel has been accounted for, according to Cambridge fire officials.

State police confirmed its troopers and the Marine Unit responded to the scene, alongside the Cambridge police and fire departments.

Boston Duck Tours told Fox News Digital that while being towed on its boat ramp, the vehicle rolled onto its side when the tow-rope broke. 

"As a precaution, we have suspended operations for the remainder of the day," the company wrote in a statement. "We are working with Massachusetts State Police and the U.S. Coast Guard to review the incident."

Since the incident happened directly at the entrance to the Charles River, Massachusetts State Police will lead the investigation.

The replica WWII amphibious vehicle is part of a fleet operated by Boston Duck Tours, a city mainstay that has conducted sightseeing tours of Boston's historic and notable sites on land and sea for over three decades.

The duck boats have been used several times in recent years to parade the region's numerous championship teams through Boston, including the New England Patriots six times, the Boston Red Sox four times, the Boston Celtics twice, and the Boston Bruins in 2011.
