WASHINGTON, Aug. 23 (Xinhua) -- Thousands of people are left without power after an explosion was reported Tuesday afternoon at a substation of the Florida Power & Light plant in west Miami-Dade County, multi TV networks reported.

Massive blaze and thick smoke billowed out of a transformer grid, leaving roads in the area closed, according to an NBS news report. Traffic could be seen backed up for miles.

The fire has caused an interruption in power for at least 10,700 Florida Power & Light customers initially. As of 4:50 p.m., about 3,500 customers remained without power, said the report.

Officials at nearby Miami International Airport said the fire caused a momentary issue but the airport was then quickly back to normal.
