Tultepec: Forensic investigators scoured the charred remains of a fireworks market outside Mexico City on Wednesday for clues to what caused a series of massive blasts that killed at least 32 people, the third fiery accident there in 11 years.
Dozens of people were injured in Tuesday`s disaster at the San Pablito open-air market, which was crowded with shoppers just before Christmas.
A smell of burning hung over the remains of the market where investigators dressed in white protective gear, police, and medical personnel searched through twisted metal frames and the wreckage of stalls. Soldiers with dogs appeared to be looking for human remains.
Alejandro Gomez, the state attorney general, told Mexican television it was unclear what caused the explosions, adding he could not corroborate accounts pointing to a detonation at one stall that may have begun a chain reaction.
Video of the blasts showed a spectacular flurry of pyrotechnics exploding high into the sky, like rockets in a war zone, as a massive plume of charcoal-gray smoke billowed out from the site.
The federal attorney general`s office opened an investigation, saying that there were six separate blasts.
Alberto Teres, owner of one of few stalls remaining, saw the flames leap from stall to stall. "The only thing you could do was run," he said.
A dozen people are still missing, Gomez said.
"It`s a catastrophe," said Guadalupe Sanchez from nearby Cuautitlan Izcalli, as she searched for her uncle, 52, who owned a market stall, and two nephews, aged 15 and 9.
It was the third time in just over a decade that explosions have struck the popular marketplace in Tultepec, home to the country`s best-known fireworks shopping and about 20 miles (32 km) north of Mexico City in the State of Mexico.
In late 2005, explosions struck the market days before Independence Day celebrations, injuring scores of people. Another explosion gutted the area again almost a year later.
A sign reading "Tultepec, Firework Capital" stood at one of the exits to the market. It was particularly full on Tuesday as many Mexicans buy fireworks to celebrate Christmas and the New Year.
Burned out cars with the paint peeled off and windows punched out by the force of the blasts ringed the site.
"Everything was destroyed, it was very ugly and many bodies were thrown all over the place, including a lot of children. It`s the worst thing I`ve ever seen in my life," said housewife Angelica Avila, 24, tears running down her face.
Avila spoke outside a nearby hospital as she waited for an update on the health of her brother, a fireworks salesman, who she said was burned and also suffered a heart attack.
Forty-six of the injured remain hospitalized, while 18 of the dead have yet to be identified due to the severe nature of their burns, said state interior minister Jose Manzur.
Investigators are studying burnt human remains at the site, but are not sure if they belong to individuals already confirmed dead, Gomez said.
Manzur said the vast majority of the market`s 300 stalls were completely destroyed. However, he noted that the site was inspected by safety officials just last month and that no irregularities were found.
