Mexico State Oil Giant Chief Not Speculating on Cause of Deadly Explosion

32 killed

A day after an explosion rocked its offices in Mexico City, Mexico's state-run oil giant Pemex says it's too early to speculate on the cause of the deadly blast.

At least 32 people—20 women and 12 men—were killed in the explosion, Pemex chief Emilio Lozoya said at a news conference Friday. More than 100 were injured, including 52 who remain hospitalized.
