A major search for two missing fishermen is set to resume at first light after their boat capsized in Loch Fyne in Argyll and Bute.
A third man was pulled from the water by the crew of a passing boat following a distress call at 18:00 on Thursday.

However, the operation was hampered by poor visibility.
A number of Coastguard rescue teams and RNLI lifeboats are expected to rejoin the search at 08:00.
The rescued man, who is in a stable condition in hospital. said two other men had been on the 40ft vessel with him when it sank near Barmore Island, north of Tarbert.
RNLI lifeboats from Tighnabruaich, Arran and Campbeltown have been involved in the search, along with the HM Coastguard Prestwick helicopter and Coastguard rescue teams from Tarbert, Kames, Inveraray and Crinan.
