Tenses with before

Should I use 'haven't happened' or 'didn't happen' in the context?

Yesterday a tragic incident happened near Delhi. At least 50 people died in a rail accident. The government and railway officials took responsibility for the accident. It is not that incidents like this/that didn't happen/haven't happened before but the number of deaths never rose/have never risen to that/this point.

Teachers,please correct my passage too if there is anything ungrammatical in it. ​

Teachers, (space after a comma) please correct my passage too, if there is anything ungrammatical in it. ​

See above.

I'd probably say "... but the death toll in a single accident has never been this high before".

You could also say:

At least 50 people were killed in a rail accident.

That's what I would expect to hear in a news report.
