Harrowing and heartbreaking.

Fourteen elementary school children and a teacher have been killed at a Texas primary school shooting.

Additionally, thirteen children and a 45-year-old male is being treated for injuries at a local hospital. The children shot dead were aged between seven and 11, according to CNN's report, and the gunman responsible for the atrocious attack was an 18-year-old local high school student.

After crashing a pickup truck outside Robb Elementary School in Uvalde, Texas, the shooter – named by Texas police and Governor Greg Abbott as 18-year-old Salvador Ramos, entered the school and started shooting.

The incident started around 11.30 am local time Tuesday.

After having killed 14 children and a teacher, plus injured several other children, Ramos was shot dead by police officers responding to the incident.

"The state of Texas is in mourning"

Holding an emergency press briefing Tuesday afternoon local time, Governor Abbott said:

"He shot and killed - horrifically and incomprehensibly - 14 students and killed a teacher."

He added:

"There are families that are in mourning right now. And the state of Texas is in mourning with them."

US President Joe Biden is today returning to the US and The White House following a trip to Asia and is expected to hold a press briefing about the incident shortly.
