Twin toddlers were killed in a house fire in Walker County, officials said.

An adult male was put into intensive care after the Monday evening fire in the Manchester community, north of Jasper, Walker County Coroner Joey Vick told AL.com.

Vick said the toddlers were 19-month-old twins -- one was a boy, the other a girl. The victims were found inside the house and will undergo autopsies to determine causes of death.

The victims' identities have not been released pending family notifications.

The State Fire Marshal's Office will help investigate the cause of the fire.
