Petróleos Mexicanos has confirmed smoke at one of its refining plants resulted from controlled burning of excess gases during unit startup.[^1]

Company sources said activation of floor burners for this purpose is a normal reaction during the procedure.

Reductions to Pemex debt interest payments will apply exclusively to the company's obligations for the 2026 fiscal year.[^2]
