Emergency responders are combing through rubble looking for possible trapped victims after a massive blast reduced a chunk of a large shopping center to rubble on Saturday at "The Fountains" shopping center in Plantation, just outside of Fort Lauderdale, Florida. It''s being reported that "multiple patients" are filling up local hospitals after what's believed to have been a gas explosion, according to early reports.
"There was a huge flash of light ... it lit up the whole sky," one witness told a local ABC affiliate. "And it was loud ... this surpassed fireworks ... your ears were ringing." The eyewitness added:
"It just looks like an apocalypse."

The cause of the blast is as yet unknown, but early reports strongly suggest a ruptured gas line may have been the cause of the blast. Local police and firefighter officials have told ABC that while initially unconfirmed, "ruptured gas lines were found in the rubble".

CNN later confirmed in a follow-up report that "a gas explosion shattered parts of a shopping mall in the South Florida city...".
