Should I use 'haven't occurred' or 'hadn't occurred' in the context?
Yesterday a tragic bus accident happened in Kolkata. At least 60 people died in the accident. The bus driver was found responsible for the accident. It is not that accidents like this hadn't occurred/haven't occurred before but the number of deaths had never risen/have never risen to that point before.
In the above context which tense I should use?
I think if I use present perfect it mean before now but as the accident happened yesterday I think I should use past perfect.
