(Reuters) - At least one person was killed and another was missing on Friday after an oil barge being pulled by a tug boat caught fire and exploded in the Gulf of Mexico off Texas, officials said.

The barge was carrying some 133,000 barrels of crude oil to a refinery in Corpus Christi when the explosion occurred at 4:30 a.m., they said.

The dead person had not yet been identified, said Rick Adams, Emergency Management Coordinator for the City of Port Aransas.

Six of the eight crew members were rescued and did not suffer any serious injuries, Adams added.

The fire was extinguished and was being monitored for re-ignition throughout the night, the Coast Guard said in a statement.

The entrance and jetty channels leading to the Corpus Christi ship channel from Harbor Island to offshore were closed to prevent the spread of discharged oil into the port and to facilitate cleanup operations, it added.

“Air monitoring has been completed by the state and confirmed to be no threat to the public,” the Coast said.

Bouchard Transportation, which owns the barge and the tug boat, did not immediately respond to a request for comment.
