A fire at a dock on the River Clyde has been tackled by crews overnight.
Rubber and aluminium being kept in the open near the King George V Dock in Govan caught alight at about 0330 BST.
Crews from Govan and Renfrew were called to the scene, where the fire service said they found a blaze covering a large area.
Attempts to get it under control and protect surrounding buildings were initially hampered by the extreme heat and limited water supplies available.
An aerial rescue pump capable of delivering large quantities of water from above the fire was requested, as well as another pump capable of lifting water directly from the River Clyde.
Crews had the fire under control by 0600 BST, having successfully prevented any further fire spread.
However, the services said it may be several hours before the blaze is fully extinguished.
As a precaution, Glasgow Airport was informed of the smoke cloud - which could be seen for several miles - and the Scottish Environment Protection Agency was also notified due to the close proximity of the fire to the River Clyde.
