Mexico: Oil plant explosion injures 30 people on Gulf Coast

MEXICO CITY (AP) — An explosion ripped through a petrochemical plant on the southern coast of the Gulf of Mexico on Wednesday, injuring dozens of people and sending flames and a toxin-filled cloud into the air.

State oil company Petroleos Mexicanos, or Pemex, said in a statement that 30 people were hurt in the afternoon blast in the industrial port city of Coatzacoalcos. By early evening the fire had been brought under control, but the company still urged people to stay away from the area as a precautionary measure.

"The cloud that emanated from the PMV plant in Coatzacoalcos is dissipating rapidly, which means it is losing its toxic effects," Pemex said via its Twitter account.

Officials canceled classes for area schools on Thursday.

Veracruz state Gov. Javier Duarte's told Milenio television that the explosion was "very strong." He said some areas near the plant had been evacuated, and recommended people remain indoors for a couple hours more.

Pemex said in a statement that the explosion happened at 3:15 p.m. at the Clorados 3 plant of Petroquimica Mexicana de Vinilo. It added that the plant is operated by another company, Mexichem, in partnership with Pemex.
