Nearly 50 guests have been evacuated from a hotel in Deeside, Flintshire, as emergency services tackle a serious fire that has engulfed the building.
Firefighters, a number of ambulances and police are at the Gateway to Wales Hotel in Welsh Road, which is on the border with England.
The alarm was raised at about 04:27 GMT and police said the fire and billowing smoke were causing significant disruption on nearby roads.
It is understood nobody is hurt.
North Wales Fire and Rescue Service said all 47 guests and a member of staff had been accounted for.
It said seven fire appliances were at the scene, along with two aerial ladder platforms.
“On arrival, firefighters found the roof space of the building well alight and used four sets of breathing apparatus, two hose reel jets and two main jets to tackle the fire,” a spokeswoman added.
“All residents and staff at the hotel have been accounted for and have been evacuated to a safe area.”
Welsh Road is closed in the area and the A494 has been closed to lorries.
North Wales Police tweeted: “Please use alternative route as long delays are expected.”
Traffic Wales said the A494 eastbound road at Queensferry was also closed because of smoke blowing across the road.
“Roads in the surrounding area are being heavily affected by smoke and are likely to close due to the safety,” it said.
The Alliance Armed Policing Unit, which works with North Wales Police, said it was supporting emergency teams at the scene.
“All blue light services at scene,” it tweeted.
Highways England also tweeted to warn motorists in England about the disruption: “#A494 is currently closed in both directions due to a building fire. .. closed from A550 and A548 junctions near Queensferry #Deeside… #M56 west traffic be aware…”
A Welsh Ambulance Service spokeswoman said: “We have resources at the scene, with four ambulances, two rapid response vehicles, two duty officers and a hazardous area response team from the North West Ambulance Service.”
