Not shootings. Killings. Some of the worst mass killings in history didn't involve a gun. The Kyoto Animation arson is a great example. Higher death count than any mass shooting in US history except for two.
However, it's virtually impossible to find a list like this. I'm specifically thinking random attacks by one or two people, so things like war crimes don't count.
I'm sick of people declaring that mass killing only happens in America. The fact that trying to Google this inevitably leads you back to lists of US mass shootings - obviously on purpose - certainly doesn't help. I don't expect to change any minds using facts and data, but it makes them feel stupid and that makes me feel better.
There are images posted of US mass shooters (3 or more victims) that include gang shootings.
I don't know of any list for mass shootings worldwide, like OP is asking for. The organizations that might compose a list would probably be biased (intelligence, UN, NGOs)
They don't keep these lists, because if they did said lists would show who the real problem is.
There were many mass shootings involving tens of thousands of victims each.
Just one Russian (Soviet) general personally shot tens of thousands people. Vasily Blokhin. His victims were all disarmed.
The Islamic State did much larger massacres elsewhere, too.
That list would be racist.
Even mass shootings happen in countries with strict gun laws. The Bataclan massacre in Paris in 2015 comes to mind. Over a hundred dead and over 400 wounded.
What’s that saying? “ lies, Damn lies, and statistics”
Biggest mass killing in American history used dynamite if I recall correctly.
I'm guessing you'd want to look up "list of terrorist attacks" for that one.
I don't think anyone will beat feminism's bioterrorism from 2020 though.
