A major search operation has been launched after a vessel overturned off the north of Scotland

Eight people are reported to have been on board the Cypriot-registered Cemfjord, a cargo ship carrying cement.

The upturned hull was found by a passing ferry in the Pentland Firth.

The search has now been called off for the night, but the Maritime and Coastguard Agency says a tug will still illuminate the area and warn shipping, until the operation resumes on Sunday.

Passengers from the ferry Hrossey spoke to the BBC about what they saw.
