A gas explosion in New York City's East Harlem neighborhood Wednesday morning sent "people flying out the windows," killing two women, injuring 22, leaving at least a dozen people unaccounted for and turning two buildings to rubble Wednesday morning, according to the New York City Fire Department and witnesses, the Daily News reports.
Mayor Bill de Blasio told reporters that the blast occurred at 9:31 a.m. and that the search continues for people still unaccounted for some three hours after the blast. A law-enforcement source told the newspaper that the cause appeared to have been a gas explosion.
Residents of a building neighboring the site complained of smelling gas at 9:13 a.m.—18 minutes before the explosion, Con Edison spokeswoman Elizabeth Matthews told the Daily News. Con Ed workers "arrived just after the explosion occurred," Matthews said.
"If we were here five minutes earlier, we may have had some fatalities among firefighters," Fire Commissioner Sal Cassano told the paper. "Not being here may have saved some lives."
A New York City Police Department source told the Daily News that nine to 12 people were missing.
Officials told the newspaper that some 250 firefighters were fighting the five-alarm blaze at the site, where two five-story buildings that contained a piano store, a church and close to 15 apartments stood before the blast.
"It's a tragedy of the worst kind because there was no indication," said the mayor.
