Death toll from Mexico petrochemical plant explosion rises to 28
Searchers have recovered four more bodies from a petrochemical plant wrecked by a huge explosion on Mexico's south-eastern Gulf coast, raising the death toll to 28.
State oil company Petroleos Mexicanos (Pemex) said some workers were still missing, but did not specify a number. It said on Thursday that eight workers were unaccounted for.
Pemex said some areas of the plant had not yet been searched. Earlier, it said drones and tracker dogs were involved in the hunt.
The company said 18 people were still in hospital. More than 130 people were injured on Wednesday when the explosion rocked the plant in Coatzacoalcos, about 370 miles south east of Mexico City.
Pemex has said the explosion happened after a leak, but has not determined the source.
The Clorados 3 plant of Petroquimica Mexicana de Vinilo produces the hazardous industrial chemical vinyl chloride.
