US President Joe Biden called Monday’s gun attack at a school in Nashville “disgusting”, adding that gun violence is tearing at the “very soul” of the United States, AFP reports.

“It’s just disgusting,” the US president said from the White House. It “tears at the very soul of our nation,” he said, praising the police response and again calling on Congress to ban assault weapons.

A 28-year-old woman killed three children and three adults at a private Christian school in Nashville, Tennessee on Monday before being shot dead by police, Reuters reported.

Armed with at least two semi-automatic rifles and a handgun, the attacker entered the school through a secondary door and fired multiple shots as he made his way into the building, Nashville police spokesman Don Aaron said.
