An explosion at a Gulf gasoline facility Friday rocked a neighborhood outside Puerto Rico's capital, causing at least some minor injuries and forcing evacuations as firefighters raced to prevent additional blasts. Authorities said the cause and the scale of the damage were not immediately clear.
FBI agents on the scene were among those investigating what caused the blast around 12:30 a.m. (0430 GMT), according to Police Chief Jose Figueroa Sancha.
Eleven of more than 30 tanks had exploded, Figueroa Sancha said. Firefighters were planning to chill the remaining tanks in an effort to keep them from exploding. Dozens of fuel trucks were also being moved from the area.
"This is about containment," firefighter Brenda Rodriguez said.
Federal Aviation Administration spokeswoman Kathleen Bergen said the agency put a temporary flight restriction in place over the area because of smoke.
Figueroa Sancha said it would likely take several days to put out the gasoline-fueled fire.
Some people who were driving through the area were injured when their car windows were shattered by the explosion, which also damaged the pavement of a highway that passes near the site.
