Gun violence has become the leading cause of death for children in America, said US Vice President Kamala Harris, adding that in the first four days of 2024, more than 400 people have lost their lives to shootings in the country.

Ms Harris took to X, formerly Twitter, to condole the death of a sixth-grade student who was killed after a teen shooter opened fire at his school in US state of Iowa.

We are thinking of the young people who have been traumatized by gun violence, and we are sending our gratitude to the teachers, staff, and members of law enforcement who quickly responded to the scene,” she wrote.

The vice president implored the US Congress and legislators to “end this epidemic of gun violence” in the country which witnessed over 650 mass shootings in schools, malls, dance studios, bowling alleys, and restaurants last year.

“We know the solutions: making background checks universal, passing red flag laws, and renewing the assault weapons ban. Now, Congress and state legislators across the country must have the courage to act,” she wrote.
