Children as young as around 11 stood in Railway Street in the north inner city of Dublin unloading fireworks and sparklers into the air as a gang of hundreds of teenagers played loud dance music as they watched the huge fire rise higher as it's flames licked the air dangerously close to hundreds of apartments.
There was a high garda presence and fire crew were nearby to monitor the fire within the small grounds of the apartments.
Mehdi Sellami, (26), from France and Ines Casarigeo, (25), from Spain, were taking an evening walk when they stumbled upon the huge fire.
"Welcome to Beirut," Ines said. "This is like a war zone. I've never seen anything like it - it's totally unorganised and dangerous and little kids are carrying and firing off fireworks."
Medhi told Independent.ie: "I used to live in this place but I moved out I came back to see at Halloween. A couple of months ago I moved out because the apartment was sold - I had no problem but for some of my room mates and some girls who came visiting us this place was not secure as their were cars being burnt out."
Ines added: "We have this tradition where I am from but not fireworks as they are illegal but this looks like war, there are little children using huge fireworks.
Mothers walked by the huge fire with children and one little girl burst into tears in her clown costume as a firework narrowly missed her.
A large number of young people who looked well under 18 were drinking larger from boxes and spirits from plastic bags as they watched the fire.
Meanwhile parents are keeping their young children far back from bonfires in the capital tonight as concerns are growing about aerosols and other dangerous products exploding.
Loud bangs are ringing out from bonfires across the north side of the city, as some adults and teenagers are throwing wooden pallets full of nails, fridges, sofas and plastic bin bags, onto vast piles to be burnt.
Darndale resident Suzanne Bollard, 41, was out at one of the fires with her friend’s young children but she was one of many adults ensuring the kids were far away from the huge infernos.
"All the kids want to come out to see the fires but at the end of the day we don’t know just what’s in them, so we keep the kids back. Everyone is keeping the youngsters safe tonight," she said.
