Authorities say a young boy has died in a fast-moving fire in a small storage shed where neighbors said children were playing behind a house on Cape Cod.

Cape and Islands District Attorney Michael O'Keefe said Monday night the boy was about 8 years old. He did not identify the child. He said the fire wasn't suspicious.

Neighbors told the Cape Cod Times two children escaped, and three children lived in the house where the shed fire broke out at about 5:30 p.m. on Hinckley Street.

John Aguiar told New England Cable News he and other neighbors tried to put out the fire with garden hoses but could not.

Fire Marshal Stephen Coan called the fire a ``horrific, tragic'' accident that ``snuffed out the life of a young child.''
