At least 1,500 ultra-Orthodox Jews stormed an Intel plant in Jerusalem on Saturday, angry that the computer chip-maker is operating there on the Sabbath. The rioters, some of whom wore shtreimels and other holiday finery, threw rocks at onlookers and journalists and ransacked part of the factory, including its chapel. According to the Jerusalem Post, protestors threw “prayer books to the floor and used prayer stands to bash in the doors.” Jerusalem’s mayor and other government officials condemned the violence and Intel-Israel CEO Maxine Fassberg pointed out that the factory has been in operation—including on Saturdays—for nearly 25 years without objection. (Blogger Neal Ungerleider offers a different account, stating the rioters stormed a new Intel plant.) Fassberg also dismissed rumors that Intel, which employs 6,500 people in Israel, would leave the country altogether if such protests continue.
