I am finally reunited with my family after 13 years. But the threat for Hazaras in Afghanistan remains

Joy flooded my heart as I finally welcomed my mother, sister and niece in Melbourne last week after 13 years of family separation as a refugee in Australia.

But I feel deep pain when I remember the day Islamist extremists killed my father, who was working as a labourer on a construction site. He was killed because of his ethnic identity as a Hazara.
