Pakistanis upset over severe electricity shortages have clashed with riot police across the country for a second day.

Officials said mobs set fire to six electricity company offices and several rooms in a police station in Gujranwala city alone on Monday. There were also reports of attacks on electricty company property in other parts of the country.

Some areas of Pakistan face power cuts for 18 hours a day. The government says it underestimated the country’s growth, but many citizens blame mismanagement and corruption for the shortages.
