Freighter carrying iron ore pellets runs aground

The U.S. Coast Guard says a freighter carrying iron ore pellets has run aground on the Canadian side of southern Lake Huron, about one mile offshore of Sarnia, Ontario. The agency there's no reports of injuries or pollution after the shipped named Buffalo ran aground late Wednesday while en route to Cleveland.

The U.S. Coast Guard is assisting Thursday in the response and sent a 41-foot boat to the scene. Sarnia is located across the St. Clair River from Port Huron, Michigan, about 55 miles northeast of Detroit.

The freighter is grounded outside of shipping lanes, which weren't disrupted. The Coast Guard is working with Transport Canada on plans to free the vessel.

The Coast Guard says the cause of the grounding is under investigation.
