Initial reports said that the breakdown was traced to a power station in southern Sindh Province that ultimately affected the entire transmission system. Officials said emergency efforts were being made to restore power, but it was not immediately clear how soon that would be. The power failure affected the capital, Islamabad, along with major cities such as Lahore, Karachi, Peshawar, and Quetta. Power was restored to parts of the capital early Sunday. The country has had chronic problems with its transmission system, and major power breakdowns have been frequent.
