Ten workers are missing from an oil rig in the Gulf of Mexico that was evacuated due to strong wind and large waves caused by Tropical Storm Nate, as dpa reported. The state-owned firm Petroleos Mexicanos (Pemex) said Friday that the workers had gone missing a day earlier. They work for Pemex subcontractor Geokenetics, a US firm, and left the Trinity II structure because it had broken and started to lean. Nothing is known of them since they left the rig. "Given the climatic conditions prevailing in the coast of Tabasco, caused by the storm Nate, the two Pemex-operated boats that are searching for them have so far not found anyone," Pemex said in a statement.
