SYDNEY (AP) — Two Australians plunged off a cruise ship into the ocean despite higher-than-required railings to prevent accidental falls, the cruise company said Friday as authorities called off the search for the couple missing for two days.

Surveillance video showed the couple going over the railing about the same time with a brief pause between them, New South Wales Police Superintendent Mark Hutchings said. It was not clear if the man or woman went overboard first, and investigators were having the video enhanced to try to learn if they jumped or fell by accident.
