New Zealand rescuers save six stranded whales

Six beached whales were successfully refloated off New Zealand Tuesday, rescuers said, after a spate of mass strandings in recent days that resulted in the deaths of dozens of marine mammals.

Wildlife rangers and volunteers used pontoons to float the killer pygmy whales -- part of a group of 12 found beached in the country's far north on Sunday -- and take them about 400 metres (437 yards) offshore.
