Public safety officials in Clearwater said Saturday night that crews responded at the Memorial Causeway Bridge when the cruise ship, known as the Pirate’s Ransom, ran aground. A second vessel attempted to take some of the passengers to shore also ran aground. Police and fireboats were taking passengers to shore late Saturday night.

A city press release says a 77-year-old woman was examined at the scene but refused treatment. There were no immediate reports of injuries.

Authorities said fog is believed to have been a factor in the ships running aground. Clearwater is located on Florida’s Gulf coast.
