Officials from the Authority for Public Services Regulation visited a power plant in Ibri, northern , to investigate the power outages thatÌýleft thousands of homes in Muscat and other areas without electricity between 1 pm on Monday and 2 am on Tuesday.

While power was restored early the following morning, the blackout causedÌýhuge disruptions in the Omani capital and dominated the news for several days after.

Videos on social media showed locals being evacuated from malls in near darkness and chaos on the roads as traffic lights went offline.

The outage came as temperatures reached 34 degrees in the capital causing discomfort for families as AC units stopped working.

Omani citizens helped divert traffic, as long queues at junctions built up, while classes and college exams were postponed.

Engineers told local media that the disruptions were the biggest the country had experienced since in 2007.

Power was fully restored in Oman at 2:22 am on Tuesday.
