Widespread power cuts have hit Iraq at a time when the country is suffering scorching summer temperatures.
The electricity cut on Friday was caused by the failure of a major power line, local media report.
The capital, Baghdad, and southern provinces have been particularly badly affected.
Protesters have taken to the streets against the outages – anger over power cuts has previously fuelled mass street demonstrations.
Earlier this week Electricity Minister Majed Mahdi Hantoosh submitted his resignation as political pressure built over repeated power cuts across the country.
Iraq's electricity ministry has cited a number of causes for the prolonged cuts. They included terrorist attacks on electricity lines, shortages of fuel for power stations, and the suspension of energy supplies from neighbouring Iran.
Crippled by US economic sanctions, Iran has been pressuring the Iraqi government to settle unpaid energy bills.

On Friday, Iraq's Prime Minister Mustafa al-Kadhimi announced urgent steps to tackle the widespread power cut. In a statement, he said he would form a committee to support the electricity ministry and "strongly confront all kinds of interference with power systems".
Most districts have been experiencing power cuts since the evening of 1 July, the Alsumaria TV network reported.

This comes as a heatwave hits the country, with temperatures reaching as high as 52C (125F). Provinces across the country's south are shortening working hours citing extreme heat.
Iraq continues to grapple with crippling power shortages, particularly during the summer, which have been exacerbated by years of conflict since the US invasion in 2003.
BBC Middle East analyst Alan Johnston said Iraq's power network has been in a dire state for years, largely on account of bad management and corruption.
