"Thankfully, there were no causalities," said a spokesperson for the ambulance service.
A Northern Ireland Fire & Rescue Service (NIFRS) Spokesperson added: "NIFRS received a call to a fire in multiple properties in Ballyduff Gardens at 17:43hrs on Saturday evening. Firefighters from Glengormley and Belfast wearing breathing apparatus used five firefighting jets to stop the spread of the fire to any other properties.
