At least two people died and 16 were injured, The New Zealand Herald . Three of the injured are being treated for serious injuries. The explosion reportedly occurred in a building where Apple's iPad 2 was being manufactured.

A video of the accident scene shows black smoke billowing from at least one building as Foxconn workers flee the area. The local fire department has the incident under control, according to an email from company spokesman Edmund Ding, Bloomberg .

The incident occurred at about 7 p.m. local time at a Foxconn subsidiary in Chengdu, the capital of southwest China's Sichuan province, according to China's official Xinhua news agency. The cause of the explosion is currently under investigation.

The Herald reports that anonymous Foxconn employees told China's Economic Observer newspaper that the blast was likely a dust explosion, which can occur when powdered, explosive material is confined in an enclosed space.

Foxconn has stopped production at the site until the investigation is complete, according to Ding, who didn't divulge which products are made at the plant. However, the Economic Observer reported yesterday that the damaged plant assembles iPad 2 tablets.
