CHICAGO (CBS) — An elderly woman was injured in an extra-alarm blaze which appeared to be sparked by children playing with fireworks in the Pilsen neighborhood.

The fire started at about 4:30 p.m. in a three-story apartment building at 1323 W. 18th St. It later spread to two neighboring buildings at 1319 and 1317 W. 18th St., according to Fire Department spokesman Will Knight.

It appeared the fire started as a result of children playing with fireworks on the third floor of a back porch, Knight said.

An 80-year-old woman suffered from smoke inhalation and was taken to University of Illinois Medical Center in “stable” condition, according to the Fire Department.
