(FOX NEWS) - An early morning house fire in western South Dakota Saturday killed five children who may have been attending a sleepover, according to reports.
The victims, ages 6 to 9, died after the fire broke out around 4:30 a.m. in a multi-family home in Spearfish, near the Wyoming border.
“What we’ve seen this morning is an unspeakable horror,” Spearfish Police Lt. Boyd Dean said, according to KELO-TV.
The station posted a video in which fire officials said at a news briefing that they heard there was a sleepover at the house, but weren’t sure.
Authorities said adults were home at the time. They tried to rescue the children and then were taken to the hospital.
