At least 21 people, including 19 children, have been killed in a school shooting at Robb Elementary School in Uvalde, Texas.

Rosa was near the school when the act occurred and tells of the horror when she saw how the children came running.

- I started to cry.

I was scared and texted my mother and my whole family that I love them, she says.

Young victims

The children killed in the shooting were between seven and ten years old.

Omar, who was also near the school, says he is angry that the victims will never be allowed to grow up and start high school.

- They should not sell weapons to those who are 18 years old, wait at least until they are 21, that is my opinion, he says.
