A breakdown in Pakistan’s national power grid has plunged the country into darkness on Saturday night.
“A countrywide blackout has been caused by a sudden plunge in the frequency in the power transmission system,” Pakistan’s Power Minister Omar Ayub Khan said on Twitter.
He said efforts were underway to determine the reasons behind the situation, and asked people across the country to remain calm.
The cities facing disruption include Karachi, Lahore, Peshawar, Multan, Quetta, Rawalpindi, Faisalabad, Muzaffargarh, Narowal, Bhakkar, Kabirwala, Khanewal, Bahawalpur and Sukkur.
The breakdown has extended as far as Azad Kashmir.
