Extension of Foxconn statement regarding impact on manufacturing operations has raised questions among the industry insiders. Several photos and videos uploaded to Chinese social media sites on Sunday evening suggest blazing in several floors of the facility.

Fire incidence in Foxconn facilities is not new. A dust explosion has taken place at a Foxconn's major iPhone making plant in the Western Chinese City of Chengdu in 2011. The fire incident has tolled three lives and injured another fifteen.

In separate event, Foxconn's listed unit and major assembling plant of iPhone, Hon Hai Precision Industry Co. has witnessed its December sales revenue to slump by a fifth and a full year. However, all the events appear amid growing concerns about slowing shipments of Apple's latest iPhone 6S models.

Apple has declined to make comments in this regard. Several huge explosions have been reported to rock the iPhone and iPad production facilities in China. Combustible dust in the air has been blamed as the cause behind those explosions. But reason behind the recent firing incident still remains unclear and seems to be mysterious.
