Children's hospital explosion in Mexico

The blast apparently was caused by a leak in the hose carrying gas from the truck to the hospital, which is operated by the city. This is a photo inside the hospital taken by Miguel Angel Salazar (@Migel_Ange). The photo of the gas tank truck was taken by @albertomty.
