Three sailors are missing and one has been taken to hospital after a fishing boat sank off the Western Isles of Scotland.
The coastguard received a distress alert just before 3.45am on Saturday, and the vessel's emergency positioning beacon was activated near Mingulay.
The vessel went down with four crew on board, but one was rescued and taken to hospital by helicopter.
A lifeboat and helicopter remain at the scene so the search can continue.
A Maritime & Coastguard Agency spokeswoman said the vessel went down in relatively calm weather conditions.
