I was at this eleventh night bonfire in East Belfast last night. It toppled over minutes after it was set alight, luckily nobody was hurt though
Also it was not far from houses in the area, but locals say they are ok with the distance between the bonfire and houses #bonfires pic.twitter.com/5f3FYyFDH0

Mid and East Antrim Council have confirmed an investigation's underway.
Green Party Cllr in Belfast, Simon Lee, says bonfires need to made safer and more environmentally friendly:
"A lot of people out there do care about the environmental impact."
"So could we do it safer, could we do it in a greener way?"
"Certainly given recent events I think the safety bit is in people's minds."
"These larger bonfires do raise some safety concerns."
