Primary sources are news reports, social media, diaries, letters, court records or other things written at the time of the event. Eye witness reports can be good sources.
With social media we have to make extra efforts to verify items with what is written in reputable news sources, keeping in mind the bias that still may exist. The same news item may have differing points based on where it is from - victims, perpetrators, government, advocacy group, etc.
For a more complete list of historical primary sources, use the Primary Sources Library Guide.
