NEW ORLEANS (AP) — A gas pipeline burned Wednesday morning in a bayou south of New Orleans hours after it was hit by a tug boat pushing an oil barge, but authorities say no oil appeared to be leaking from the barge.

Coast Guard Cmdr. Russ Bowen said it appears the barge is intact and none of its cargo of crude oil was leaking, though there were patches of oily sheen in the area. The Coast Guard was investigating whether those sheens were related to the accident.
