A Norwegian Cruise Line ship with more than 3,500 people on board has been refloated after running aground near Bermuda.

The Norwegian Dawn was returning to Boston with 2,443 passengers and more than 1,059 crew.

It is believed to have temporarily lost power after leaving port.

A spokesman for Norwegian Cruise Lines said: "The ship's propulsion was affected and, at which time, the vessel made contact with the channel bed."

However the vessel has now been refloated after high tide.

A spokesman for the cruise line said the boat will remain anchored off Bermuda overnight.

Experts will inspect it on Thursday before it returns to Boston.
