INTERNATIONAL NEWS - The death toll from a fire at a northern Mexico oil refinery has risen to four, the oil company said Sunday, after another worker succumbed to his injuries.
The fire broke out Friday at the complex in Ciudad Madero, a city bordering the US state of Texas, just two weeks after another blaze at the same refinery.
State-run energy company Pemex said on Twitter that the workers were doing maintenance work on a coker unit when the accident took place. The firm said the unit was out of service and did not suffer material damage.
On Sunday, the oil company announced the latest toll and added that seven injured workers also remain hospitalized.
One worker died Friday, and two other workers died earlier Sunday, Pemex said.
A fire injured 23 workers at the same refinery in the state of Tamaulipas on July 24.
Mexico's Congress finalized a landmark energy reform on Wednesday aimed at modernizing Pemex's facilities and ending the company's 76-year-old monopoly on drilling by opening the sector to foreign investment.
