Another duck boat accident in Boston

State police say six people are being treated for minor injuries after an amphibious "duck boat" crashed into several cars on a Boston highway.

Trooper Thomas Murphy said the accident happened at about 12:15 p.m. on Friday on a ramp connecting to Storrow Drive. He said seven vehicles were involved and that the injured people were taken to hospitals.

The accident follows a separate incident in Boston on Tuesday in which one person was taken to the hospital after a car became wedged between a duck boat and delivery truck.

A fleet of 28 World War II-era duck boats are used by Boston Duck Tours for tours by land and water.
