BATON ROUGE, Louisiana -- Flames burst into the sky on this Louisiana interstate in the middle of the night, sending fire and smoke rolling into the air over Baton Rouge.
The source, a damaged tanker, was part of a multi-vehicle accident that caused a traffic nightmare on an inner-state highway yesterday.
Crews set off this controlled burn to get rid of leaking isobutane -- an extremely flammable gas.
Firefighters controlled the flames nearly two hours later.
People living nearby were temporarily evacuated.
