A fire broke out early Thursday after an explosion at an Oklahoma oil refinery, authorities told NBC News.
A Tulsa Police Department spokesperson confirmed to NBC News that they were notified about the fire at the HollyFrontier refinery in west Tulsa at 2:21 a.m. local time (3:21 a.m. ET).
The refinery has its own fire department, which was battling the fire, and local authorities were on standby in case they were needed, the spokesperson said.
The local and corporate offices of the Dallas-based HollyFrontier Corp. could not immediately be reached. An employee who answered the telephone at the Tulsa refinery could not provide comment.
The flames reached several stories into the air immediately following the explosion but had since died down, according to a reporter on the scene from NBC affiliate KJRH-Tulsa. The glow from the fire could be seen from several miles away, KJRH reported.
Local radio station KRMG reported that local residents stood outside their homes and watched the flames rise into the air.
No injuries have been reported.
