Emergency services are battling to free children and employees trapped in a collapsed school in Mexico City.
When the magnitude 7.1 earthquake struck central Mexico on Tuesday, the Enrique Rebsamen primary school collapsed alongside dozens of other buildings in the capital.
At least 21 children and five adults present in the school died in this event, and others are believed to be missing.
Rescue operations to move rubble and free the trapped occupants of the destroyed building entered their second night on Wednesday.
A thermal scan of the ruins revealed a number of those trapped to be still alive, and anxious parents have gathered to hear news of their children.
The president of Mexico, Enrique Pena Nieto, has declared three days of mourning for the victims of the disaster, which killed at least 225 people and injured hundreds of others.
