Nashville victims: three nine-year-olds and school head among six shot dead

Three children at the Covenant School in the Tennessee capital were shot dead on Monday, the 129th US mass shooting this year

Three nine-year-old children and three adults arrived at the Covenant School, a small, private Christian academy in Nashville, Tennessee, on Monday for what appeared to be a normal day of school.

Before noon, all six had been killed - the victims of a shooter who terrorized the school with multiple firearms before being shot dead by police.
