Production has been suspended at the Foxconn factory near Chengdu in southwestern China until police complete an investigation into the cause of the blast, which happened at about 7 p.m. local time Friday, the Journal reported.
Local media have said in the past that Apple’s iPad tablet computer is manufactured at the Foxconn facility, but an Apple spokesman was not immediately available for comment.
The Chengdu municipal government confirmed in a statement that two people are dead and 16 injured, including three seriously, but the government appears to be ruling out foul play as a cause.
Video posted to the Internet shows people fleeing as clouds of black smoke billowed from the sprawling facility.
Foxconn is the trade name of Taiwan-headquarted Hon Hai Precision Industry Co., the world’s largest contract manufacturer of electronics.
