Five killed, six missing in helicopter crash

Five people were confirmed dead tonight and six were missing after a civilian helicopter plunged into the sea 25 miles north-east of Great Yarmouth.

Eleven people were on board the aircraft, two of them crew and the rest oil rig workers, rescuers said.

It is not yet known why the helicopter went down and a spokesman for RAF Kinloss, north Scotland, which is helping coordinate the rescue, said weather conditions were good.
