Gas leak sparks Vic home evacuations

More than 15 houses have been evacuated and a 100 metre exclusion zone has been put in place as emergency crews deal with a gas leak in Melbourne.

Workmen using earth moving equipment on a nature strip near Broadway and Lindsay Street in Reservoir, in Melbourne's north, are said to have damaged the gas line, the MFB says.

Firefighters are using water spray to disperse the gas vapour, while the public is advised to avoid the area.
