Four die as explosion flattens Mexico children's hospital

Rescuers are searching for survivors of a powerful gas explosion that shattered a maternity and children’s hospital in Mexico City, killing at least three adults and one baby while injuring dozens more.

Claudia Dominguez, a spokeswoman for the city’s civil defence agency, confirmed the deaths from the gas tank truck explosion, but said she could not verify a report by a local borough chief, Adrian Rubalcava, that seven had died.
