Major blackout hits Australian city

The northern Australian city of Darwin has been hit by a major power blackout, forcing schools to close and knocking out traffic lights. The power cut, which was caused by a tripped circuit at a sub-station, affected all of Darwin and towns up to 300km away. Government offices were closed for the day and the bus network was affected. Power was eventually restored more than 12 hours after the outage began in the early hours of Wednesday, according to BBC.
