How many international tourist deaths are terrorism related? [closed]

Worldwide, over the past couple of decades (maybe since October 9 1995 if you need to be exact), how many deaths of international tourists are terrorism-related?

Either absolute numbers (eg 12,345 people total), or relative (eg 12 deaths per 100,000 tourists, or alternatively 1.2% of all international tourist deaths) is acceptable.

I tried doing a google search for "terrorism risk international tourism", but only came across papers researching the impact of terrorism on tourism.
