Sinn Féin Councillor for the area, Colly Kelly expressed alarm over the incident.
He told the Journal: “I would like to commend the quick response from the fire service for extinguishing this fire so quickly .
“It must have been a very frightening experience for those living so close the site of the fire.
“ It’s disappointing to learn that after the initial fire was put out that is was started again a short time later and the fire service had to be called out for second time.”
