Boy, 14, commits suicide after school shooting

US police officers have been seen running into a Cleveland high school where a suspected shooter is a 14-year-old student who was apparently upset about a suspension.

A 14-year-old student opened fire injuring three teenagers and two adults before killing himself at an American high school today, US authorities said.

Cleveland mayor Frank Jackson said two boys, ages 14 and 17, and two men, ages 42 and 57, were injured in the shootings at the SuccessTech Academy in Cleveland, Ohio. A 14-year-old girl fell and hurt her knee while running out of the school.
