A new survey says the cost of conflicts reached a record $14.3 trillion in 2014, equivalent to 13.4 percent of the world’s gross domestic product.
The 2015 Global Peace Index, published on June 17 by the Australia-based Institute for Economics and Peace, says that amount is equivalent to the combined economies of Brazil, Britain, Canada, France, Germany, and Spain.
Syria ranks as the least peaceful country in the index, while Iceland remained the most peaceful.
The Middle East and North Africa now ranks as the world's most violent region, overtaking South Asia.
The study says 180,000 people were killed in conflicts in 2014, compared with 49,000 in 2010.
The cost of supporting refugees and internally displaced people has increased by 267 percent since 2008 to $128 billion as the numbers of uprooted people topped 50 million -- the highest level since World War II.
