An explosion at a fireworks market outside Mexico City has killed at least 31 people, officials say.
More than 70 others were injured as the blast hit the San Pablito fireworks market in Tultepec, about 20 miles (32km) outside the city.

Are silvester celebrations really worth the risk of handling badly packaged explosive devices to civilians?

Every year people seem to lose eyes, hands and sometimes even lives just to let something explode in the air or even on the ground and have it fall back down as trash that they won't clean up.

Number of serious injuries in the US each year by fireworks 9,300

Would it not be wiser to have these explosives handled by professionals who make fireworks for the entire city to see?

That is taking the easily-made assumption that some kind of fireworks mishandling was the cause of this and not some evil intent.
