A mobile home has killed three children and left their father with serious arm burns from trying to save them, Louisiana fire officials said.

State Fire Marshal's Office spokesman Mike Delaune says a 12-year-old girl, an 11-year-old boy and a 9-year-old boy died at the Whispering Oaks Trailer Park in Houma.

Houma Fire Inspector Mike Millet says the trailer was engulfed in flames when firefighters arrived after 1:30 a.m. Wednesday.

He says the children's father rescued one child, but was unable to get the other three because the fire spread so quickly.

Investigators haven't determined the cause.

Millet says eight people were inside the trailer because the children and their parents were visiting from Alabama for Christmas. No one else was hurt.
