At least 31 dead, 72 hurt in Mexico fireworks market blast

Mexico : A massive explosion gutted Mexico's biggest fireworks market on Tuesday, killing at least 31 people and injuring 72, the authorities said.

The conflagration in the Mexico City suburb of Tultepec set off a quick-fire series of multicolored blasts that sent a vast cloud of smoke billowing over the capital.

The market had been packed with customers buying pyrotechnics for traditional end-of-year festivities. Christmas and New Year parties in many Latin American countries often wrap up with clattering firework blasts.

"You just heard the blast. And everything started to be on fire. People came running out on fire," Walter Garduno said.

"People were alight -- children," he added before trailing off.

From a few kilometers (miles) away, the multiple explosions that started at 2:50 pm (2050 GMT) almost looked festive, alight in blue, red and white. They were anything but.

Of the 31 confirmed dead, "26 (died) at the scene and five in hospitals," local media reported Mexico's chief prosecutor Milenio Alejandro Gomez as saying.

Forensic experts are working on genetic analyses of the bodies because "almost all of them are impossible" to identify, Mexico state's governor Eruviel Avila told the Televisa television network.

At least 72 were wounded, the authorities said. The injured were transported to emergency rooms, and 21 have since been released.

Fire crews struggled for three hours before bringing the blaze under control.
