MEXICO CITY, Rajab 14, 1437, Apr 21, 2016, SPA -- An explosion killed 13 people and injured scores at a petrochemical plant on Mexico's southern Gulf coast. The blast and ensuing fire caused evacuations in the area as a fire billowed a toxin-filled cloud into the air. According to AP, the head of Mexico's civil defense agency, Luis Felipe Puente, wrote in his Twitter account Thursday that emergency personnel had been able to enter the burned-out plant and found ten more cadavers. Three workers had been reported dead immediately following the blast Wednesday afternoon. The state oil company, Petroleos Mexicanos, said 136 workers had been hurt in the blast in the industrial port city of Coatzacoalcos. Eighty-eight of the injured remained hospitalized. --SPA 16:12 LOCAL TIME 13:12 GMT www.spa.gov.sa/w
