ISIS attacks are on the rise

2015 compared to the previous three-month period, both in terms of the number of non-militant casualties and the frequency of attacks.

Jane's reported 1,086 separate attacks between July 1 and September 30 of this year, or a daily average of 11.8 daily. That's up from 8.3 last quarter, representing an increase of 42%.

The attacks killed 2,978 non-militants, a 65% increase from the previous quarter.

Jane's concludes that the true number of attacks was likely "far higher," as the agency relies on open-source intelligence and only reports what can be confirmed definitively by governments, or attacks claimed by the ISIS militants themselves.
