A Vietnam War veteran died after carrying his three-year-old granddaughter to safety following a gas explosion at his home in Oklahoma.

Don Osteen, 69, who was awarded the Purple Heart for bravery during his time in the Army died on Monday from complications during surgery, his son said.

Brendon Osteen said his father Don was lighting a candle next to a stove at his home in Maud, Oklahoma when there was a powerful gas explosion.

Don’s granddaughter, Paetyn was severely injured in the blast suffering burns on 30 per cent of her body.

Before he died, Don told his wife that the roof also fell on top of Paetyn and he was stopped from fleeing the scene to get help because his keys had melted and phone exploded because of the heat.

"He was an old man who shouldn't have been able to do what he did," Brendon Osteen told CNN.

"After saving my daughter's life, he then hiked up a driveway that goes a quarter of a mile through the woods and through and back up a steep creek bed," Brendon said

A GoFundMe page set up by the family said Don suffered burns on 78 per cent of his body, a collapsed lung and broken ribs.
