The number of accidents caused by fireworks on the eve of the Lunar New Year fell in Beijing this year, local authorities said Thursday.

In the hour from midnight on Wednesday to 1 a.m. on Thursday, there were 25 accidents and 22 injuries caused by fireworks, down by 14 percent and 24 percent respectively from last year, said Liu Zhi, director of a municipal governmental office overseeing fireworks.

Some 83,000 boxes of fireworks were sold in Beijing on Wednesday, a decrease of 34 percent, and more than 10,000 boxes of illegal fireworks were confiscated.

The fireworks made Beijing's smog worse. The municipal environment bureau said pollutants rapidly increased from 8 p.m. on New Year's eve sufficiently to cause "heavy pollution" at midnight.

Beijing deployed over 7,200 firefighters and 811 fire tenders from 6 p.m. on Wednesday to 8 a.m. on Thursday to prepare for any possible fires. Endi
