Firefighters have tackled a blaze at a tower block in Dunmurry.
The Fire Service, Ambulance Service, and police attended the scene.
The fire at Coolmoyne House tower block on Seymour Hill has been brought under control.
A spokesperson for the Northern Ireland Ambulance Service said four people have been taken by ambulance from the flats.
A Northern Ireland Fire and Rescue Service spokesperson said a man was rescued from the fire and a number of others taken to safety.
It received a call at 5.32pm, and a total of eleven fire appliances attended the scene.
"On arrival the Fire & Rescue Service were faced with a well-developed fire on the ninth floor of a block of flats," the spokesperson said.
"The prompt intervention of our fire-fighters quickly brought the blaze under control and it was extinguished at 6.10pm. One person has been rescued and a number of residents were led to safety.
"Crews remain on scene dealing with the incident. The cause of the incident is currently under investigation.
"The Fire & Rescue Service are still in attendance and would like to reassure the public that this incident does not provide any further risk to the public."
It is understood the cause of the fire was connected to a toaster.
A witness at the scene confirmed hundreds of residents had been evacuated to the street, with the local community hall operated by Seymour Hill and Conway Community Residents Association opened.
Julie Ann Jackson from the Seymour Hill and Conway Community Residents Association said the fire broke out in the flat of a man in his 50s who lived alone, who was able to alert other people in the building about the fire.
Speaking about concerns of the residents, she said: “I think they were shook up from Grenfell, and after tonight they are really shook up.”
A spokesperson for the Housing Executive - which manages the Coolmoyne House tower block - told the Belfast Telegraph it was an "evolving situation" and it had staff present at the scene.
He added the Housing Executive was "waiting to see from the Fire Service if the tenants will be able to return to their flats, and if they will have somewhere to stay tonight".
Representatives praised the efforts of emergency services who dealt with the fire.
Former firefighter Robbie Butler, the Ulster Unionist MLA for Lagan Valley said members of the Fire Service had shown "immense bravery and professionalism in getting residents out of the flats so quickly to be treated by the paramedics".
"Social media pictures offer a glimpse of the terrifying scene which faced residents, and emergency services who arrived at the flats," he said.
"I know from experience what races through your mind when you first arrive at the scene of a fire. Given the tragic images and terrible loss of life which we saw at Grenfell earlier this year, people are very aware of the potential for loss of life in circumstances like this. Thank goodness on this occasion, that was not the case."
SDLP MLA Pat Catney, who was present at the scene, said residents were "frightened and in shock at what they witnessed this evening".
"We do need to understand urgently what happened here tonight to provide reassurance to those affected. I'll continue to work with the Northern Ireland Housing Executive to ascertain further information," he said.
Writing on Twitter, DUP MP Sir Jeffrey Donaldson said after Grenfell assurances had been sought about the safety at Seymour Hill and Conway, and said he had spoken to the Secretary of State James Brokenshire about carrying out a full investigation.
