CORPUS CHRISTI, Texas (AP) — Firefighters in Corpus Christi responded Friday to an apparent explosion in the city’s port and refinery district.

A fire was reported about 8 a.m. near Nueces Bay in the northern part of the city and crews were on the scene, Fire Chief Robert Rocha told KIII-TV. Flames and a large plume of black smoke were visible.

Rocha did not immediately return a phone call seeking comment and it was not immediately clear what exploded or if there were any injuries.
