2,000 workers at a Chinese factory broke into violence on Monday, halting to supply of one of the leading electronics manufacturing plants, including Apple. Yahoo news is reporting that as many as 40 people were injured as a result of a huge fight that broke out at Foxconn in China.

As of right now, the police do not know what caused the violence, but it is under investigation. This will be a big blow to people who like gadgets, and the companies that sell them. The factory was shutdown, but will reopen on Tuesday.

Foxconn makes iPhones and iPads for Apple, and also manufactures several things for Microsoft, and HP.
