Two babies and eight other young children were among the 24 people killed by a tornado that tore through the Oklahoma City suburb of Moore.

The babies aged four and seven months old died in Monday's fierce twister that steamrollered entire neighbourhoods and two schools in the Oklahoma City suburb of Moore.

"Our hearts go out to all the people affected by this tragedy," Amy Elliott of the state medical examiner's office said in an email detailing the revised breakdown of the official death toll. Previously, authorities had put the number of child fatalities at nine.
