Norway police says no survivors yet found after helicopter crash

OSLO (Reuters) - No survivors have so far been found following the helicopter crash off the coast of Norway on Friday, police told Reuters. Some 13 people were on board the helicopter, which was on its way to shore from Statoil's Gullfaks B platform in the North Sea. "We have not found any survivors. We are still looking," said Morten Kronen of the region's police force. "We are searching a large ocean area." Statoil separately said it had temporarily grounded all helicopters of the type that crashed. (Reporting by Ole Petter Skonnord, writing by Terje Solsvik, editing by Gwladys Fouche)
