Mexico’s Pemex said three workers are still missing after a platform fire that killed four other workers last week.
Pemex said rescue operations are ongoing for three workers who were aboard the Abkatun Permanente processing platform when it was engulfed in flames last Wednesday.
The names of the missing workers have not been released.
“The search is ongoing, and so is the support of the Mexican navy. We won’t stop until we’ve found them,” Pemex general director Gustavo Hernandez said during a press conference.
The platform was operating in the Bay of Campeche when a blaze broke out at its dehydration and pumping area, prompting the evacuation of 301 workers.
Forty five workers required medical attention with two workers still listed in serious condition.
Pemex said there was no evidence of a major spill and that a small amount of hydrocarbon runoff was contained by a specialized vessel.
Mexico’s attorney general has opened an investigation into the accident that could lead to criminal charges including property damage and homicide.
Mexico’s National Agency of Industrial Security and Environmental Protection for the Hydrocarbon Sector (ASEA) is also investigating the accident.
