Mexico City hospital: Aerial video shows blast devastation

A gas tank lorry has exploded outside a maternity and children's hospital in Mexico City, killing a woman and a baby, the city's mayor said.

The explosion, on the western edge of Mexico City, was so large that much of the building was destroyed.

The BBC's Katy Watson visited the scene and said there was a sense of shock at what had happened.
