According to a study, deaths due to terrorist attacks on the West have increased by 650 percent in a year.
According the annual Global Terrorism Index report, the rise is associated with socio-economic factors including youth unemployment and distrust in the electoral process.
The increase in the 34 countries within the OECD (Organisation for Economic Co-operation and Development) came despite a 10 percent drop in terror-related deaths globally in 2015, reports The Nation.
The report said that military interventions against Islamic State (IS) and Boko Haram reduced terror deaths in Iraq and Nigeria but jihadis spread to other regions.
More than half of the 577 deaths in the West were carried out in allegiance with the Islamic State, the study, produced by the Institute for Economics and Peace (IEP), said.
Steve Killelea, executive chairman of the IEP, said: "The attacks in the heartland of Western democracies underscore the need for fast-paced and tailored responses to the evolution of these organisations."
