List Notes: Data is top 5 worst terrorist attacks in modern history. Death toll includes victims only and does not include the death of the perpetrator(s).

Please note: death toll statistics can be difficult to verify and therefore these numbers should be considered as a close estimate. The Top 5 of Anything does not attribute terrorist attacks to any particular religion but rather to organizations who may use religion as a means to achieve their political objectives. Terrorist attacks are considered to be non-military objectives which are perpetrated on civilians intending to cause mass casualties. Please note that other terrorist attacks have occurred that may be omitted from this list as data is difficult or impossible to verify such as attacks in Nigeria and Cameroon perpetrated by groups such as Boko Haram.
