NEW YORK CITY -- Firefighters and rescue crews continue to comb the rubble following Wednesday morning's massive explosion and double building collapse in Harlem.
New York City officials say the body of an eighth victim was recovered from the debris Thursday evening.
Dozens more are recovering from their injuries and the search continues for the people who are still unaccounted for.
Authorities say the explosion happened about 15 minutes after a neighboring resident reported smelling gas.
The two, five-story residential buildings that were leveled housed a Spanish Christian Church and piano repair shop on the ground level.
A gas leak is being blamed for the explosion.
The city evacuated residents in the area to help the more than 250 firefighters that responded.
Mayor Bill De Blasio was back on scene Thursday morning to get an update from the FDNY.
"The response by the fire department and all the other agencies involved has been extraordinary. I hope all the people affected take some solace in the fact that every effort has been expended to address this crisis and search for their loved ones," the mayor said.
Officials are also working to get displaced families from adjacent buildings back in their homes.
