A fire which engulfed seven derelict buildings in Larne's town centre may have been started deliberately, the fire service has said.
About 50 firefighters attended the blaze in Larne's town centre
Fifty firefighters were needed to tackle the blaze in the town's Main Street.
About 20 families were moved out of their homes and traffic was severely disrupted for a number of hours.
Divisional Officer Gordon Latimer said the fire was brought under control fairly quickly.
"We had the fire under control fairly quickly, although there were buildings quite close by with elderly residents that we had to evacuate," he said.
"Three of those elderly residents might have suffered smoke inhalation, other than that there are no injuries."
Main Street has been re-opened, but Quay Street will remain closed until Saturday morning.
