TORONTO (AP) — A cruise ship exploring the Northwest Passage in the Arctic has run aground on a rock that wasn't on the map.

Robert Bradbury of the Canadian Coast Guard said on Sunday they got the call about the stranded Clipper Adventurer late on Friday. Bradbury says the icebreaker Amundsen has been dispatched to the area and is expected to start removing passengers within a couple of hours.

He says there are 197 people on board and no one is reported injured.

The passengers will be moved via the icebreaker to Kugluktuk, Nunavut, about 50 nautical miles away.

The 90-metre cruise ship is operated by Ontario-based Adventure Canada. The company says efforts by the crew to dislodge the vessel were unsuccessful and now rests with a slight list.
