UPDATE: The cause was determined to be accidental. The fire was started by workers using a blowtorch.

Although the flames are not entirely extinguished, a fire at the Universal lot in Los Angeles is now contained. The blaze, which erupted around 5 a.m. this morning has injured four firefighters. It has also damaged approximately 4-5 structures including New York Street, Courthouse Square, the video vault and the building that houses the King Kong exhibit.

While no cause has yet been determined, it is believed filming was going on at the time.

The fire, located at the backlot near the theme park, should not interrupt tonight’s taping of the 2008 MTV Movie Awards.
