A fire at a Pennsylvania day care center early Sunday killed five children, including four siblings, officials said.

Four people were injured, including two teenagers who jumped from a second-floor window onto a porch of the home in Erie to escape the flames, Erie Fire Chief Guy Santone told CNN in an interview. Santone said the homeowner was injured, along with a neighbor who tried to enter the burning home to rescue victims.

Eight people were in the home when the fire broke out around 1:15 a.m., Santone said. The home also operated as a day care, according to fire officials.

"I was just down there, there's flowers everywhere," Santone said about a memorial at the scene. "Nobody likes to see this, especially when it's kids."
