In light of the December 16, 2014 suicide bombing and armed assault at the Army Public School in Peshawar, Pakistan by the militant group Tehrik-i-Taliban Pakistan (TTP), START researcher and GTD program manager Erin Miller has authored a new background report, titled "Terrorist Attacks on Educational Institutions" using information from the Global Terrorism Database. The report describes historical patterns of terrorist attacks targeting educations institutions dating back to 1970. Since that year, more than 3,400 terrorist attacks targeting educations institutions took place in 110 countries. These attacks comprised 2.7 percent of all terrorist attacks worldwide during this time period.
