Fireworks explosions killed many people and injured hundreds more in China as the 2006 traditional Lunar New Year celebrations led to much disorder as well as joy across the nation.

At a temple fair in Henan, 36 people were killed on New Year's Day when a nearby storeroom full of fireworks exploded. The accident, caused by 3 children who threw burning fireworks into the storeroom, injured up to 48 people.

In the capital, Beijing, where a 12-year ban on Lunar New Year fireworks had just been lifted, the government reported 112 people were treated at hospital emergency rooms over the weekend for fireworks-related injuries.

"On New Year's Eve alone, we had more than 40 injuries and among them there were around a dozen people with serious injuries," hospital assistant director,Tian Jian said. In China's south-western city, Chongqing, where the fireworks ban was also lifted after 12 years, firefighters rushed to put out nearly 200 fires caused by fireworks on New Year's Eve.

A ban on fireworks, which are traditionally believed to ward off evil spirits and ghosts trying to enter New Year, was put in place across 200 cities in China due to safety and environmental pollution concerns. The ban was lifted in Beijing and many other cities in 2006.
