Pakistan's government has ordered an inquiry into the cause of a nationwide power cut that plunged the country into darkness for a few hours.
The electricity network broke down on Sunday after a power plant in south-western Balochistan province developed a technical fault, officials say.
The cities of Islamabad, Lahore, Peshawar and Rawalpindi were among those affected.
Power cuts are common in Pakistan, but a nationwide failure is rare.
