A toddler had been playing with his twin brother before he was killed when they were both hit by a learner driver on Brisbane's Bayside.
The three-year-old boys were struck by a reversing car driven by a 16-year-old at Thorneside in Brisbane's east at 3.35pm on Saturday.
One of the children suffered serious chest and head injuries, but tragically he could not be saved, a Queensland Ambulance spokesperson confirmed to Yahoo News Australia.
His surviving brother was taken to hospital with minor injuries, and remains in a stable condition.
The teenage driver of the car was hospitalised for shock, reportedly suffering severe emotional distress.
The Courier-Mail reports a witness heard the mother of the boys scream "no", before holding the unresponsive little boy in her arms.
Witnesses said the pair had been playing in the large gated residential complex.
About 7.30pm a tow truck left Bayview Court, at the Bayside Central complex, carrying a Toyota Corolla Ascent with L-plates, according to the newspaper.
No charges have been laid and investigations are continuing, a police spokesperson confirmed to Yahoo News Australia on Sunday.
