School Shooting in California

Two young girls were injured in a school shooting Friday by a man who fired several shots at a Carlsbad, California elementary school.
The gunman stood on the sidewalk next to the playground and fired several shots into a group of elementary school kids, the Los Angeles Times said.
The man was quickly tackled by nearby construction workers who restrained him until authorities arrived, USA Today said.
The two girls' injuries were not life-threatening and the Los Angeles Times said the gunman's shots grazed the two girls' arms.
Witnesses said the man seemed to be carrying a gas tank, USA Today said.
