Mother tells police: 'I killed my babies'

A US woman whose two young sons were found dead in their home told police "I just killed my babies," officers said.

San Antonio police reported the brothers, aged one and three, had been stabbed.

Their 22-year-old mother was calm as she greeted officers who responded to an emergency call from the house on Tuesday. A police spokesman said the boys were next to each other, dressed and on a bed, and “looked like they were sleeping”.
