Four people are being treated in hospital after a fire broke out at a five-star hotel on the banks of Loch Lomond.
Dozens of firefighters were called to Cameron House at around 6.40am on Monday.
Two adults and a child, believed to be from one family, were taken to hospital in Glasgow for treatment, while a fourth patient was taken to the Royal Alexandra Hospital in Paisley.
Pictures on social media showed guests and staff standing outside the hotel while emergency services took control of the area.
Firefighters could also be seen tackling the blaze in the roof of the hotel from an aerial unit.
A spokesman for the Scottish Ambulance Service said: "We received a call at 6.44am today to attend an incident at the Cameron House Hotel.
"We dispatched four ambulances, our special operations response team and the trauma team to the scene.
"Three patients, two adults and one child, were taken to the Queen Elizabeth University Hospital.
