Matthew McConaughey has said the spate of mass shootings across America is 'an epidemic we can control' as he paid tribute to the victims of the atrocity in his Texas hometown of Uvalde.
At least 19 children and two adults have been reported dead after a teenage gunman opened fire at Robb Elementary School in Uvalde on Tuesday.
The devastating shooting is the deadliest at a US primary school since the infamous Sandy Hook shooting in Newtown, Connecticut, where 20 children and six adults were killed in 2012.
The 18-year-old male, who has been identified as Salvador Ramos, was killed on the scene after reportedly being shot by responding officers.
Following the tragedies, Hollywood actor Matthew, 52, has called for urgent gun law reform in America.
The actor, who shares three children, with wife Camila Alves, said he thought about his own children when he heard about the devastating shooting.
Taking to Twitter, the How To Lose A Guy In Ten Days star - who is originally from the town of Uvalde - condemned the use of guns across the US.
“As you all are aware there was another mass shooting today, this time in my home town of Uvalde, Texas," he penned.
“Once again, we have tragically proven that we are failing to be responsible for the rights our freedoms grant us.”
The Hollywood actor went on: "This is an epidemic we can control, and whichever side of the aisle we may stand on, we all know we can do better. We must do better.
“Action must be taken so that no parent has to experience what the parents in Uvalde and the others before them have endured.”
“And to those who dropped off their loved ones today not knowing it was goodbye, no words can comprehend or heal your loss, but if prayers can provide comfort, we will keep them coming.”
Other stars including James Corden, Taylor Swift, Amy Schumer and Kylie Jenner also expressed their 'rage and grief' in the wake of Tuesday's shooting.
Addressing the shooting in a monologue on The Late Late Show on US television, TV host Corden said that on the issue of gun laws, America is 'one of the most backward places in the world'.
"When I dropped my kids off at school this morning and kissed them goodbye, it doesn't cross your mind that that could ever be the last goodbye," he said.
"And the thought of that phone call, that your child is the victim in a mass shooting is beyond comprehension as a human being," James added.
Meanwhile, popstar Taylor Swift shared a video of Golden State Warriors coach Steve Kerr, who delivered an emotional message in a press conference before the NBA western conference finals.
"Filled with rage and grief, and so broken by the murders in Uvalde," she wrote in an emotional tweet.
"By Buffalo, Laguna Woods and so many others. By the ways in which we, as a nation, have become conditioned to unfathomable and unbearable heartbreak. Steve's words ring so true and cut so deep."
