Students at Santa Fe High School protested against guns less than a month ago

America has been rocked by another high school shooting, this time claiming ten lives.

On Friday morning a man, who police suspect to be 17-year-old Dimitrios Pagourtzis, entered a classroom at Sante Fe High School, Texas and opened fire.

He is believed to have been armed with a shotgun and a .38 revolver which belonged to his father. He is now being held by police on capital murder charges.

This is now the 22 school shooting to have taken place in the United States in 2018 and comes just months after the devastating Marjory Stoneman Douglas shooting in Parkland, Florida on 14 February.

That incident resulted in the deaths of 17 people but managed to kick-start a movement by young people who were asking for stronger gun laws to be enforced in America.

This included huge events organised by the survivors in Parkland like the historic March For Our Lives and various school walkouts which inspired students across the US.

One of the most sobering points to have emerged from the Santa Fe shooting was that a number of students at the school had taken part in a walkout just 28 days prior to yesterday's shooting.

This photo was shared by City University of New York professor Angus Johnston who also runs the website Student Activism.

The walkout which took place on April 20 to coincide with the 19 anniversary of the Columbine massacre saw the group observe 17 minutes of silence and also read out a poem by one of the Parkland survivors.

The tragic image soon went viral and people offered their thoughts in response.
