GRAY, Ky. (AP) — The uncle of one of seven people killed in a house fire in southeastern Kentucky says he tried to rescue them but was too late.

Gino Cima ('SEE-mah) said Sunday that he made it to the single-story house within minutes of hearing the news Saturday morning and found two bodies by a side door.

Cima says one body was of his adult nephew, and it appeared he had been headed to a room where five young children were sleeping. The other was of his nephew's pregnant fiancée.

He says he then raced to the front of the house, but the children's bodies were already lined up in the yard.

Officials have not identified the victims, but family members say the five children killed ranged in age from 10 months to 3 years. The cause of the blaze has not been released.
