Another American school shooting has made international headlines after 17 people were killed north of Miami, Florida.

But this is far from the first school shooting in the United States so far this year.

The Everytown for Gun Safety Support Fund says America has averaged one school shooting a week since 2013, based on the definition "any time a firearm discharges a live round inside a school building or on a school campus or grounds".

In 2018 so far the rate has been far higher, with Everytown putting the number of school shootings at 17 before the Florida attack.

Not all of the shootings resulted in injuries or deaths. But here are five that did.

A 15-year-old girl was shot in a Texan school cafeteria on January 22, 2018

She was shot by a 16-year-old classmate at a school in the small town of Italy.

The shooting sent dozens of students in the cafeteria scrambling for safety.

"I was pretty scared," Edgar Eduardo Rodriguez, a 15-year-old student, told KWTX News.

"This is a small town, you know? I never imagined it."

Police told reporters that the shooter was confronted by a school staff member. The 15-year-old was recovering in hospital and in "good spirits" after the shooting, officials said.

"It is an amazing demonstration of her strength that she was able to survive this," school district superintendent Lee Joffre said.

This was the first fatal school shooting of 2018. A 15-year-old student fired a handgun at classmates at the rural Marshall County High School in Kentucky.

"He was determined. He knew what he was doing," said Alexandria Caporali, a student who grabbed her stunned friend and ran into a classroom during the attack.

Two 15-year-old students — a boy and a girl — died and seventeen students were injured.

Ms Caporali said the shooter kept firing until he ran out of ammunition and took off running, trying to get away.

Police arrested a suspect moments later, leading him away in handcuffs to be charged with murder and attempted murder.
