'This could have been us,' survivor of Christchurch shooting speaks of aftermath

For 29-year-old Ashir Rizvi, a survivor of a mass shooting last week in Christchurch, the past week has been a "roller coaster of emotions". Rizvi was with his friend and flatmate at a mosque in the Linwood neighbourhood just beginning Friday prayers on Mar. 15 when a lone gunman arrived, shooting bullets through the windows at the worshippers inside.
