TULTEPEC, Mexico -- A powerful chain-reaction explosion ripped through Mexico's best-known fireworks market on the northern outskirts of the capital Tuesday, killing at least 29 people, injuring scores more and sending a huge plume of charcoal-grey smoke billowing into the sky. Video of the blast showed a dramatic staccato of rockets exploding in flashes of light, levelling the open-air San Pablito Market in Tultepec in Mexico State as it bustled with shoppers stocking up on fireworks to celebrate Christmas and New Year's. Vendors' stands were reduced to piles of rubble, ash, and charred metal. It was the third devastating explosion and fire to ravage the market since 2005 and officials still have not said what caused this latest blast. Crescencia Francisco Garcia said she was in the middle of the grid of stalls along with a few hundred others when the thunderous explosions began. She froze, reflexively looked up at the sky and then took off running through the smoke once she realized everyone was doing so. As she ran she saw people with burns and cuts, and lots of blood. "Everything was catching fire. Everything was exploding," Francisco said. "The stones were flying, pieces of brick, everything was flying." In comments broadcast on local TV news, Mexico State Gov. Eruviel Avila reported Tuesday night that in addition to the 26 people who perished at the market, three more victims died after being taken to hospitals. State Health Secretary Cesar Nomar Gomez Monge said 72 people were being treated for injuries including severe burns, in some cases over 90 per cent of their bodies. Those hospitalized included 10 children. Authorities said an investigation into the tragedy had been opened. "We are going to identify who is responsible," Avila said. Sirens wailed and a heavy scent of gunpowder lingered in the air well after the explosion at the market, where most of the stalls were destroyed. The smoking, burned out shells of vehicles ringed the perimeter, and first responders and local residents wearing blue masks over their mouths combed through the ash and debris. Firefighters hosed down still-smouldering hotspots. Tultepec Mayor Armando Portuguez Fuentes said the market was especially well stocked because demand for noisy firecrackers and rockets soars this time of year. "We are obviously in the high season," Portuguez said. "There was more product than usual because we are a few days away from Christmas, a few days away from New Year's, and those are the days when the products made here are consumed the most." Cesar Ornelas of Atizapan de Zaragoza was only 10 minutes into shopping with his son and his father when he heard the first explosions. He tried to run, but something knocked him to the ground from behind. He tried several times to get up, unsuccessfully, and ultimately his 15-year-old son Francisco had to drag him out. "We didn't look back," said Ornelas, who suffered light burns and a large bruise over his left kidney. His white tank top had a fist-size burn on the chest. "We heard how the explosion was kind of going off bit by bit." Nearly four hours later, he and Francisco limped gingerly out of the market area. Francisco said paramedics told him his leg was likely fractured by flying debris. Ornelas said his 67-year-old father, Ernesto, had run in a different direction and sought refuge in a nearby home. All the father's clothing was burned, and his face and arm were bloodied. An ambulance had spirited him to a hospital, but Ornelas wasn't sure where it was or how serious his injuries were. "My condolences to the families of those who lost their lives in this accident and my wishes for a quick recovery for the injured," President Enrique Pena Nieto said via Twitter. A similar fire engulfed the San Pablito Market in 2005, touching off a chain of explosions that levelled hundreds of stalls just ahead of Mexico's Independence Day. A year later a similar incident at the same market also destroyed hundhundreds
The bodies of some of the 31 people killed in an explosion at a fireworks market outside Mexico City are so badly charred that neither their age nor gender can immediately be determined, the state prosecutor has said. Alejandro Gomez said that, so far, only 13 bodies had been identified. He said forensic experts were now carrying out DNA tests to identify the blackened remains of the dead. More than 70 people were also injured when the explosion happened. Among them were three badly burned children who are due to be taken to a hospital in the US for treatment. The site of the market resembled a wasteland on Wednesday The blast and accompanying series of smaller explosions caused devastation at the San Pablito fireworks market in Tultepec, located close to Mexico City. It is estimated that about 80% of some 300 stalls in the market were destroyed. An investigation into the causes has been ordered by the attorney general's office. It said the incident began with six initial explosions, followed by a series of chain reactions. But Mr Gomez said he had no idea at present what triggered the disaster. "I have no theories for now," he said. "Our priority has been to attend to the injured, remove the bodies and deal with the emergency." Locals on Wednesday have been told to avoid the area and keep roads clear. The market was reduced to charred wreckage Survivors have spoken of "hellish scenes" as fireworks took off in all directions, causing panic and destruction. The main part of the fire is reported to have lasted at least three hours. The disaster took place as the market was crowded with revellers buying fireworks in advance of Christmas and New Year celebrations. Tultepec is seen by many Mexicans as "the country's capital of pyrotechnics", the Washington Post reported, with thousands of people attending the biggest festival in March - which consists of a firework display and bulls rampaging through the streets. The San Pablito market was heavily damaged by similar fires in September 2005, when a chain of explosions just before the country's independence day celebrations injured dozens of people.
