Four seafarers have been airlifted from a grounded cargoship off Norway.

Video from the Norwegian Society for Sea Rescue showed the listing 600-dwt Osfjord (built 1967) being battered by waves off Afjord.

It was en route from Bergen on Saturday when the incident occurred.

A helicopter took the men off the vessel after it sent an emergency signal.

The ship is operated by Osfjord Bulk of Norway.
