Much of Chile was in the dark Sunday after a widespread blackout knocked out power to 90 percent of the country, CNN's sister network in the country reported.
The blackout was caused by a failure to the country's central electric system, but it was unclear what led to the failure, CNN Chile reported, citing Chilectra, a power company that provides electricity to the capital, Santiago.
Subway service was also affected, CNN Chile said, but all passengers had been evacuated from stopped trains as of Sunday night.
The blackout comes two weeks after a massive 8.8-magnitude earthquake struck the country, killing more than 500 people. Aftershocks as high as magnitude 7.2 continue to disrupt recovery efforts.
