Horror as 35 children die in nursery inferno.
Frantic parents rushed to the ABC day care centre in the city of Hermosillo in Sonora state, which borders Arizona in the US.
They joined firefighters in a desperate fight to reach those trapped inside through the building's only exit as others raced to hospitals, desperate for news on their children.
One dad crashed his truck through the wall to rescue his child.
Most of the young victims died of smoke inhalation as rescuers battled to reach them.
Grieving Delfina Ruelas, 60, broke down outside the morgue as she told how four-year-old grandson German Leon died from his burns.
She said: "They operated on him but he couldn't hold on." There were about 100 children - ranging in age from six months to five years - in the nursery.
Firefighters took two hours to control the blaze. The cause is still unconfirmed but it is believed it may have been started at a neighbouring tyre and car warehouse..
