Two firefighters have been killed after a tree fell on their vehicle at the scene of a major fire in Victoria's north-east, a union says.
The Department of Sustainability and Environment (DSE) firefighters were believed to have been killed near Harrietville, south of Bright, where a bushfire is currently burning out of control.
The Australian Workers Union Victorian branch has said two men died in the line of duty at a fire in the Ovens region today but authorities have not confirmed the information.
It is believed the men were on the western edge of the blaze at Pheasants Creek Track when a tree fell on their 4WD, Nine News reports.
The accident took place late this afternoon and police and ambulance officers travelled to the scene.
The Country Fire Authority (CFA) has warned the bushfire is yet to be contained.
The identities of the men have not been released.
