A crying mother who lost her 14-year-old daughter, Alyssa Alhadeff, in the Marjory Stoneman Douglas High School shooting has screamed at US President Donald Trump to "do something" about student safety.
Lori Alhadeff had just organised her daughter's funeral arrangements when she delivered a highly emotional plea to Mr Trump on CNN.
"The gunman, a crazy person, just walks right into the school, knocks down the window of my child's door and starts shooting, shooting her, and killing her," she said on CNN.
"President Trump, you say 'what can you do', you can stop the guns from getting into these children's hands.
"What can you do? You can do a lot. This is not fair to our families that our children go to school and have to get killed."
She finished with a furious and emotional plea for Trump to: "Do something. Action. We need it now. These kids need safety now."
Mr Trump tweeted his condolences following the shooting and he also raised the incident in a White House speech, but avoided discussing gun control.
Authorities said an ex-student, identified as Nikolas Cruz, walked into the Marjory Stoneman Douglas High School in Parkland, near Miami, on Wednesday and opened fire with an AR-15-style assault rifle.
He was charged with 17 counts of premeditated murder after being questioned for hours by police for the second-deadliest shooting at a public school in modern US history.
