More than 1 million without power in Puerto Rico after fire causes major blackout

More than a million customers in Puerto Rico remained without electricity on Thursday after a fire at a main power plant caused the biggest blackout so far this year across the U.S. territory, forcing it to cancel classes and shutter government offices.

The blackout also left some 160,000 customers without water and snarled traffic across the island of 3.2 million people, where the roar of generators and smell of diesel filled the air. Those who could not afford generators and have medical conditions such as diabetes, which depends on refrigerated insulin, worried about how much longer they'd be without power.

Long lines formed at some gas stations as people sought fuel for generators. Others tried to charge their cellphones at businesses in scenes reminiscent of the aftermath of Hurricane Maria, which struck as a Category 4 storm in 2017.
