The world’s wealthiest nations experienced the worst year in over a decade for terrorist attacks and deaths in 2015.
Organization for Economic Co-operation and Development countries suffered 731 attacks, a 23 percent increase from its previous high in 2004 after a steady rise over the past six years, according a new report by the Institute for Economics and Peace, which has been collecting data since 1997. Meanwhile Iraq, Nigeria, and Pakistan -- which account for a third of total incidents worldwide -- each declined by more than 20 percent.
