Sydney  - A drunk driver who let his sons die alone after a crash lost an appeal against his eight-year jail sentence in a Brisbane court Saturday.

Alan Ross, 27, was drunk, had no licence and was travelling at twice the speed limit when he rolled his car after losing control.

He ran from the scene of the accident, leaving his dying infant sons behind.

Ross claimed the sentence was too severe, but the court dismissed his appeal, saying it was important to acknowledge the gravity of the offence. (dpa)
