A section of Union Street was cordoned off for more than two hours after a fire broke out within a city centre vape store.
A total of seven appliances were tasked to the scene after the blaze broke out shortly after midday.
Smoke could be seen billowing from the Refill Station shop, an e-liquid provider, as well as neighbouring stores.
Witnesses also claimed they seen firefighters cutting into the basement below Refill Station to seek out the source of the flames.
The area was cordoned off with yellow tape between Back Wynd and Belmont Street as crews descended on the area.
A section of The Green was also sealed off, to the rear of the premises.
In a statement, a fire spokesman said: “We were alerted at 12.07pm on Monday, March 11 to reports of a fire at a building on Union Street, Aberdeen.
“Operations Control mobilised seven appliances to the scene where firefighters are working to extinguish the fire.
“Crews remain on scene.”
Union Street has now reopened as crews begin to leave the scene.
Properties evacuated following shop fire
Crowds gathered along the street to watch events unfold as the busy city centre street was brought to a standstill.
Crews from Aberdeen, Banchory and Oldmeldrum were tasked to the scene, alongside a command support unit.
The stop message was received at 2.05pm.
Police Scotland officials said they had been made aware of the incident.
Surrounding properties were evacuated by firefighters as they worked to locate the source of the blaze.
Staff barely had time to put their shoes on as fire took hold
Staff from a dental practice, located in the same building, said they heard the fire alarm go off before evacuating the premises.
They said: “We haven’t been told anything.
“We smelled smoke and the fire alarms went off around 12.20pm.
“We were told we were to evacuate by firemen immediately.”
Next door, Mobiles, Gadgets and Vapes also fell victim to the fire as smoke built up in the store.
Speaking at the scene, manager Malik said staff barely had enough time to put their shoes on as smoke began to build up in the shop.
He said: “There’s a fire round the back of the Refill Station store next door.
“They say they are going to have to break the window from the back and enter that way.
“Both theirs and our shop is completely closed.
“My staff member didn’t even have time to get his shoes before we had to evacuate.”
Fire crews were seen entering the Refill Station store from both the Union Street entrance and the rear door, backing onto The Green.
Firefighters wore breathing apparatus as they scoped out the source of the fire.
