1 killed, 11 injured in blast at oil refinery in northern Mexico

MEXICO CITY—Mexico’s state-owned oil company says one worker died when a gas leak caught fire and shot out flames at a refinery in the northern state of Tamaulipas.

Petroleos Mexicanos, known as Pemex, said the blast Aug. 8 also injured 11 workers at the refinery in Ciudad Madero.

The company said the blast happened at a coker plant that wasn’t operating because of maintenance work being carried out at the time of the accident.

The blast didn’t start a bigger fire and the installations were not damaged.

Pemex said experts will investigate what caused the accident.
