An explosion at a winery in Australia has led to the deaths of two men this week.

Trevor Drayton and one other man, thought to be a welder, were killed when an explosion rocked the family-owned Drayton's Winery in Hunter Valley yesterday (17 January). The blast, which demolished 20m of brick wall at the property, is believed to have been triggered by the igniting of ethanol gas during a welding operation.

A third person was taken to hospital by air from the facility, at Pokolbin in New South Wales, suffering from burns to 80% of their body.
