A heated row has reached boiling point in Australia over a suspected gas leak that has left a major river increasingly flammable.
The Condamine River in the state of Queensland has been captured bubbling while the lighting of a match brought flames dancing across its surface.
A leak of methane was first claimed to have seeped into the Condamine near Chinchilla in 2012.
Landowner John Jenkyn posted several photos to Facebook of a phenomenon that locals claim has intensified over the past few months.
The Australian government told the national broadcaster the ABC it remained unsure of what had caused the seeps following a series of investigations over the past few years.
Locals have renewed calls for Queensland officials to launch a fresh investigation to determine the cause of the bubbling.
