Around 20 people were injured, including two seriously, when a significant explosion Saturday morning erupted at an LA Fitness and several other stores of a Plantation, Florida, strip mall west of Fort Lauderdale, according to law enforcement officials.
Authorities believe it was a gas explosion. The impact sent large pieces of debris about 100 yards across the street.
Joel Gordon, deputy chief of the Plantation Fire Department, said approximately 20 people have been treated for injuries, two of whom were hurt seriously. At least one of them is facing life-treating injuries, he said. He didn't know how many were taken to the hospital. No fatalities have been reported.
"We believe we have accounted for everybody at this point," he said. "We're still searching the collapsed area for anybody else."
He added: "This is still active. It's still going."
Gordon stressed the explosion appears to be a gas explosion but that it hasn't been confirmed.
Gordon said several stores, including the LA Fitness, were severely damaged.
Video and photos posted on social media showed a destroyed business with damaged buildings next to it.
The Plantation fire and police departments said on Twitter that the street was closed to traffic.
