The joint rescue co-ordination centre in Halifax says a 24-member crew is being rescued from a container ship about 60 kilometres south of Portugal Cove
Spokesman Maj. Martel Thompson says the centre received a call around 11:30 a.m. local time Sunday that the vessel was having issues with its hull.
Thompson says two Cormorant helicopters from Gander, N.L., are on scene, as well as a Hercules aircraft from Greenwood, N.S., and a Coast Guard ship is en route.
He says several people have already been safely hoisted into a helicopter from the ship, which is still floating on water.
Thompson would not say where the ship is from.
