'It's just a nightmare': Ten-year-old victim's mum speaks at Bondi memorial

The mother of 10-year-old Matilda, the youngest victim of the Bondi Beach attack, paid tribute to her daughter at a flower memorial on Tuesday evening.

Matilda's mother Valentyna told the mourners that the family came to Australia from Ukraine more than a decade ago – adding the family thought it would be a safe place for them.

Fifteen people were killed in the attack on Sunday, and dozens more were injured.
