KIM Kardashian is among a host of celebrities calling for tighter gun controls after a gunman went on a rampage at a school in Florida on Valentine's Day.
Expelled student Nikolas Cruz, 19, returned to Marjory Stoneman Douglas High School armed with an assault rifle and opened fire at students and teachers.
Chilling images posted on Instagram show the shooter, who remains in police custody, posing with guns and knives as fellow pupils admit they "knew he would shoot up the school".
His actions prompted the likes of singer Nancy Sinatra, talk show host Ellen DeGeneres and actress Reese Witherspoon to call for stronger gun restrictions in the wake of the atrocity on Wednesday.
The Keeping Up With The Kardashian's star called on the US government to do more to protect children and teachers.
Writing on Twitter, she said: "We owe it to our children and our teachers to keep them safe while at school. Prayers won't do this: action will.
"Congress, please do your job and protect Americans from senseless gun violence."
Actress Julianne Moore tweeted: "The 18th school shooting in the US since January. It is heartbreaking. What will it take to change our nation's gun laws ???"
Nancy Sinatra called on the Republican Party to pass "sensible" gun laws immediately.
She added: "Seventeen more of our young people dead, killed by a shooter with an automatic weapon he had no business having."
Florida Governor Rick Scott, a Republican, said it was an act of "pure evil" but refused to discuss gun controls in a press conference on Wednesday night.
Broward County Sheriff Scott Israel earlier said that the suspect had at least one AR-15 rifle and multiple magazines.
While some fatalities were found outside the building, most were inside, he added.
