He opened fire unexpectedly, creating panic and casualties in a matter of seconds.
Authorities also confirm that the perpetrator of the attack has died.
"Two young children, aged eight and ten, were killed as they sat on benches. Their parents have been notified of their tragic loss," said O'Hara, who described the attack as a brutal act.
In total, according to authorities, 17 people were injured, 14 of whom are children, two of whom are in critical condition.
