A maternity hospital south of Mexico City is in danger of collapsing after a natural gas explosion set it on fire Thursday. At least two people are dead, with more than 54 people believed to have been injured — including 22 children — and an unknown number of individuals trapped. Mexico City Mayor Miguel Angel Mancera explains, “The truck was supplying gas to the hospital when apparently a hose burst and the resulting leak caused an explosion,” CNN reports. Preliminary reports detail that the initial injuries were minor, as medical teams treated cuts from flying glass from the explosion. However, at least eight people are seriously injured. Updated information remains unconfirmed at this time.
