Two-year-old dies in Beenleigh house fire

Paramedics are treating four people after the fire at Beenleigh

A toddler has died on his second birthday in a house fire in south-east Queensland.

The boy's mother and four children escaped the blaze that destroyed the Beenleigh house just before 3pm Thursday.

Police said the fire occurred while the father was picking up a sixth child, the eldest, from school.

"The mother was home with the other five and she got four out," Acting Inspector John Hamrey told reporters.

"The other little fella, a son, the two-year-old, was in the back part of the house and she couldn't get to him.

"We believe it was his birthday today."

Television footage of the incident showed the father being held back while apparently trying to re-enter the burning home.

The QAS spokesman said a man was treated at the scene for mild smoke inhalation.

Acting Inspector Hamrey said it was unclear what sparked the blaze.

Investigations are continuing.
