Happening Now just reported on this story moments ago.

WEST COTE BLANCHE, La. (AP) -- Coast Guard officials say they are investigating a fire at an oil drilling platform off the coast of Louisiana.

A parish officials says the rig is not drilling at a deepwater site like the Macondo well that blew out in 2010. That blowout led to an explosion that killed 11 workers and led to the worst offshore oil spill in U.S. history.

Jefferson Parish Councilman Chris Roberts tells WWL-TV that the platform is a shallow water platform in the Gulf of Mexico. It is near West Cote Blanche Bay, south of New Iberia on the south-central Louisiana coast.

The Coast Guard says it has activated a command center to investigate the fire. The size of the fire was not immediately clear, nor was it known if there were any injuries.
