WASHINGTON (Reuters) - The number of people killed in militant attacks worldwide jumped more than 60 percent last year to a record high of nearly 18,000 and the figure could rise further in 2014 due to an escalation of conflict in the Middle East and Nigeria, a report showed on Tuesday.
Four Islamist groups operating in Iraq, Syria, Afghanistan, Pakistan and Nigeria were responsible for two thirds of the 2013 attacks and the vast majority of the deaths occurred in those countries, the Australia and US-based Institute for Economics and Peace (IEP) said in its Global Terrorism Index.
