It's a flaming mystery
BAFFLED builders unearthed a muddy mystery, after the foundations of a factory filled with flaming mud.
Pools of fire appeared on a building site in eastern China after builders sunk deep holes for foundation rods.
Wei Lei, a 38-year-old bricklayer told the Austrian Times: "The next morning the holes were had dug were full of a dark, rich liquid mud that felt hot when you leant over it,
"Then someone threw a lit cigarette in there and it went up like a torch and has been burning for more than a week now."
Experts have been left stumped by the fires but believe the workers may have accidentally tapped into unknown oil or natural gas reserves.
