MEXICO CITY (Reuters) - Mexico's government vowed on Friday to find out whether an explosion that killed 33 people at the headquarters of its state-run oil monopoly Pemex was a deliberate attack or yet another stain on the company's poor safety record.

Rescue workers continued to pull bodies from the debris on Friday and officials said the search would continue until everyone inside the Mexico City building was accounted for.

Government officials have refused to speculate over what caused the explosion on Thursday but said they were keeping an open mind and had deployed large teams of experts to pore through the wreckage.
